CHILDREN, OBEY YOUR PARENTS IN THE LORD: Ta tekna, hupakouete (2PPAM) tois goneusin humon [en kurio]: (Genesis 28:7; 37:13; Leviticus 19:3; Deuteronomy 21:18; 1 Samuel 17:20; Esther 2:20; Proverbs 1:8; 6:20; Proverbs 23:22; 30:11,17; Jeremiah 35:14; Luke 2:51; Colossians 3:20-25)   (Eph 6:5,6; Romans 16:2; 1 Corinthians 15:58; Colossians 3:16,17,23,24; 1 Peter 2:13) 

Paul continues to emphasize the importance of Spirit filled believers in interpersonal relationships, particularly as the Spirit's control is evidenced by a submissive spirit in the believer, in this case believing children. As discussed below Paul does not use hupotasso which describes submission between equals (husband and wife) but hupakouo which speaks of one who is not the other's equal (this same usage being applied to master/slave relationships). By the way, don't misinterpret this verse. Yes, the primary instruction is to believers, children and parents, but that does not mean that children are to obey parents only if their parents are believers!

Johnson puts this section dealing with children in a proper cultural perspective writing that...

The callousness of the Roman Empire with respect to children throws this into very broad relief because, just as in our society today, the signs of breakdown were not only in the Roman Empire, but had come to pass. And in their society, children were unwanted. They were abandoned. They were mistreated. They were abused. They were raped, and furthermore, they were murdered. Everyone of those experiences are experiences that are characteristic of our society today. So, the Apostle’s words were addressed to a society that was very much like ours: it did not have concern for children. (Ephesians 6:1-9 Paul to Children & Fathers Audio)

Barclay adds that...

Under the patria potestas a Roman father had absolute power over his family. He could sell them as slaves, he could make them work in his fields even in chains, he could punish as he liked and could even inflict the death penalty. Further, the power of the Roman father extended over the child’s whole life, so long as the father lived. A Roman son never came of age. Even when he was a grown man, even if he were a magistrate of the city, even if the state had crowned him with well-deserved honours, he remained within his father’s absolute power. “The great mistake,” writes Becker, “consisted in the Roman father considering the power which Nature imposes as a duty on the elders, of guiding and protecting a child during infancy, as extending over his freedom, involving his life and death, and continuing over his entire existence.” It is true that the father’s power was seldom carried to its limits, because public opinion would not have allowed it, but the fact remains that in the time of Paul the child was absolutely in his father’s power. There was the custom of child exposure. When a child was born, it was placed before its father’s feet, and, if the father stooped and lifted the child, that meant that he acknowledged it and wished it to be kept. If he turned and walked away, it meant that he refused to acknowledge it and the child could quite literally be thrown out.

A Roman baby always ran the risk of being repudiated and exposed. In the time of Paul that risk was even greater. We have seen how the marriage bond had collapsed and how men and women changed their partners with bewildering rapidity. Under such circumstances a child was a misfortune. So few children were born that the Roman government actually passed legislation that the amount of any legacy that a childless couple could receive was limited. Unwanted children were commonly left in the Roman forum. There they became the property of anyone who cared to pick them up. They were collected at nights by people who nourished them in order to sell them as slaves or to stock the brothels of Rome. (Barclay, W: The Daily Study Bible Series, Rev. ed. Philadelphia: The Westminster Press)

It was into such an upside down world that the Gospel shined forth to light the way for children to be set free from this horrible darkness and despair.

Boice has the following introductory comment...

Norman Corwin wrote in an article for Reader’s Digest entitled “Perfect Home”: “One child makes a home a course in liberal education for both himself and parents; two children make it a private school; three or more make it a campus.” But many parents today are not sure that they are up to being professors in this university, and even then they are unsure of what should be offered in the curriculum. (Boice, J. M.: Ephesians: An Expositional Commentary)

Obedience and honor sum up the whole distinctive duty of the child, not just in the New Testament but also in the Old, the latter recording that...

Leviticus 19:3 'Every one of you shall reverence his mother and his father, and you shall keep My sabbaths; I am the LORD your God. (Note that in Lev 19:3-4, three of the Ten Commandments are reiterated as being particularly important - concerning parents, sabbaths, and idolatry).

Deuteronomy 21:18 "If any man has a stubborn and rebellious son who will not obey his father or his mother, and when they chastise him, he will not even listen to them, 19 then his father and mother shall seize him, and bring him out to the elders of his city at the gateway of his home town. 20 "And they shall say to the elders of his city, 'This son of ours is stubborn and rebellious, he will not obey us, he is a glutton and a drunkard.' 21 "Then all the men of his city shall stone him to death; so you shall remove the evil from your midst, and all Israel shall hear of it and fear. (Comment: Morris writes that "Records indicate no rebellious son was ever put to death under this law. Every father elected to spare his own son, no matter how sinful the son might have been. Only Christ, the perfectly obedient Son [John 8:29;17:4] was not spared [Ro 8:32] [Ref]).

Proverbs 1:8 Hear, my son, your father's instruction, And do not forsake your mother's teaching;

Proverbs 6:20 My son, observe the commandment of your father, And do not forsake the teaching of your mother; 21 Bind them continually on your heart; Tie them around your neck. 22 When you walk about, they will guide you; When you sleep, they will watch over you; And when you awake, they will talk to you. 23 For the commandment is a lamp, and the teaching is light; And reproofs for discipline are the way of life,

Proverbs 23:22 Listen to your father who begot you, And do not despise your mother when she is old.

Pr 30:11 There is a kind of man who curses his father, And does not bless his mother.

Pr 30:17 The eye that mocks a father, And scorns a mother, The ravens of the valley will pick it out, And the young eagles will eat it. (Their body will lie unburied for the birds to feed on)

Colossians 3:20 Children, be obedient (present imperative) to your parents in all things, for this is well-pleasing (well approved, eminently satisfactory, or extra-ordinarily pleasing) to the Lord. (see note) (Comment: In the ancient world children were very much under the domination of their parents. The supreme example was the Roman Patria Potestas, the law of the father's power. Under it a parent could do anything he liked with his child. He could sell him into slavery; he could make him work like a laborer on his farm; he had even the right to condemn his child to death and to carry out the execution. All the privileges and rights belonged to the parent and all the duties to the child.)

To disobey parents is a symptom of a disintegrating, decaying society, and Christian families have a distinct responsibility not to contribute to the collapse of the ordered community. To disobey parents is named in the horrible list of sins ascribed to those with who "did not see fit to acknowledge God any longer" and who God therefore gave "over to a depraved mind, to do those things which are not proper"...

slanderers, haters of God, insolent, arrogant, boastful, inventors of evil, disobedient to parents (See notes Romans 1:28; 1:29; 1:30)

Paul says parental disobedience will characterize the last days writing...

But realize (present imperative)  this, that in the last days difficult times (grievous times, violent, fierce, wild, hard to bear times) will come. 2 For men will be lovers of self, lovers of money, boastful, arrogant, revilers, disobedient  (apeithes = literally those who refuse to be persuaded!) to parents, ungrateful, unholy (See notes 2 Timothy 3:1; 3:2) (McGee observes that "Disobedience to parents is the last and lowest form of lawlessness to occur on this earth. Disobedience to parents is one of the characteristics of the last days. Today we hear of many cases of children rejecting parental authority and even killing their parents! This is indicative of the times in which we live." [Ref])

Children (5043) (teknon teknon from tikto = bring forth, bear children, be born) is strictly a child produced, male or female, son or daughter. Teknon is thus a child as viewed in relation to his or her parents or family. In the plural, teknon is used generically of descendants, posterity or children.

Note that another Greek word huios (5207), translated son, differs from teknon because the latter gives prominence to the fact of birth, whereas huios stresses the dignity and character of the relationship and usually speaks of one who is fully mature. Despite these distinctions, because these words often overlap in meaning and are used seemingly without discrimination, one should not press their semantic differences in every case but allow the context to rule in the interpretation (always a good rule!)

Teknon is used 100 times in the NAS (Matthew 12x; Mark 7x; Luke 14x; John 3x; Acts 5x; Romans 5x; 1 Corinthians 3x; 2 Corinthians 2x; Galatians 5x; Ephesians 5x; Philippians 2x; Colossians 2x; 1 Thessalonians 2x; 1 Timothy 5x; 2 Timothy 2x; Titus 2x; Philemon; 1 Peter 2x; 2 Peter; 1 John 4x; 2 John 3x; 3 John; Revelation 3x) and is translated: child, 13; children, 76; children's, 2; son, 8; sons, 1.

Teknon is used some 142 times in the Septuagint (LXX) (Gen. 3:16; 17:16; 22:7f; 27:13, 18, 20f, 25f, 37, 43; 30:1; 31:16, 43; 32:11; 33:6f; 43:29; 48:19; 49:3; Exod. 10:2; 17:3; 20:5; 34:7; Lev. 25:41, 46; Num. 14:18, 23; 16:27; Deut. 2:34; 3:19; 5:9; 11:19; 21:17; 22:6; 24:16; 28:54f, 57; 29:29; 32:5; 33:24; Jos. 14:9; 22:24, 27; Jdg. 18:21; 1 Sam. 1:8; 2:5, 24; 3:9, 16; 4:16; 6:7, 10; 14:32; 24:16; 26:17, 21, 25; 30:22; 1 Ki. 8:25; 9:6, 15; 12:24; 15:4; 17:12f, 15; 20:3, 5; 1 Chr. 2:30, 32; 22:7; 2 Chr. 25:4; 28:3; 30:9; 33:6; 35:7; Ezra 8:21; Neh. 12:43; Est. 3:13; 7:4; 9:25; Job 5:25; 21:8; 39:4, 16; Ps. 34:11; 78:4; 109:13; 113:9; Prov. 7:7; 14:26; 17:6; 30:4; 31:2, 26; Isa. 2:6; 13:16, 18; 14:21; 27:6; 29:23; 30:1; 39:7; 44:3; 51:18; 54:1, 13; 57:4f; 60:4, 9; 63:8; Jer. 2:30; 3:19; 19:2; 31:17, 29; 32:18, 39; 35:14; 38:23; Ezek. 5:10; 16:21, 36, 45; 18:2; 20:18, 21; 23:37, 39; Dan. 6:24; Hos. 1:2; 2:4; 4:6; 5:7; 9:12f; 10:9, 14; 11:1, 10; 13:13; Joel 1:3; 2:23; Mic. 1:16; Zech. 9:13; 10:7, 9) (Hint: Download InstaVerse to allow you to quickly survey these uses)

Teknon was used in secular Greek writings as a form of familiar, tender or affectionate address to speak of one kindly even if they were adults referring to them as "my son" or "my child". For example Jesus speaking to the paralytic declared

"Take courage, My son (teknon), your sins are forgiven." (Mt 9:2)

In the NT, pupils or disciples are called children of their teachers, because the latter by their instruction nourish the minds of their pupils and mold their characters. For example Paul writes...

For this reason I have sent to you Timothy, who is my beloved and faithful child (teknon) in the Lord (see notes 2 Timothy 1:2), and he will remind you of my ways which are in Christ, just as I teach everywhere in every church. (1Cor 4:17) (Comment: In his first epistle Paul writes as a spiritual father "to Timothy, my true child [teknon] in the faith: Grace, mercy and peace from God the Father and Christ Jesus our Lord." 1Ti 1:2. In Titus Paul again writes as a spiritual father "to Titus, my true child  [teknon] in a common faith: Grace and peace from God the Father and Christ Jesus our Savior." see note Titus 1:2 )

Teknon takes on special theological significance when the Bible calls believers the children of God (Click here for NT uses of this wonderful phrase - note one use by Paul is not of those who are born again and uses genos -- "offspring" -- not teknon in the Greek text  - see if you can determine which one is not referring to the born again members of the family of God) or more literally "born ones" of God. In using teknon in this context the NT is not saying believers are "childlike" but tat we are members of God's family as thus heirs, Paul affirming...

and if children (teknon), heirs also, heirs of God and fellow heirs with Christ, if indeed we suffer with Him in order that we may also be glorified with Him. (See notes Romans 8:17)

Teknon is used in a number of phrases in the NT, and one must examine the context to determine whether the phrase refers to believers or non-believers -- "children of the flesh" (unsaved Jews - see note in Romans 9:8), "children of the promise" (Jews who have placed their faith in the Messiah - see note in Romans 9:8), "children of the desolate" (those saved by grace through faith, Gal 4:27), "children of promise" (any believer in Messiah, Jew or Gentile, Gal 4:28), "children of the bondwoman" (unbelievers in Gal 4:31), "children of wrath" (unbelievers - see note in Ephesians 2:3), "children of light" (believers - see note in Ephesians 5:8), "children of the devil" (unbelievers - 1John 3:10 - read this text which clearly divides all of humanity into one of two camps).

Teknon views the child in relation to his parents or family and this use is especially significant in the New Testament, in which we see all of mankind divided into one of two families from a spiritual standpoint  -- either the family of God or the family of the Devil. As such we can apply the common saying "Like father, like son". In one of the most scathing discourses of Jesus against the Jews (who had "believed" in Him in John 8:30, but not with a belief unto salvation as context shows, eg, these same Jews "picked up stones to throw at Him" in John 8:59) we read the following interchange

They (the Jews who had "believed" in Jesus) answered and said to Him, "Abraham is our father." Jesus said to them, "If you are Abraham's children (teknon), do the deeds of Abraham." (John 8:39) (Comment: Read this entire incredible exchange -- John 8:30-59 -- where Jesus goes on to declare that these "believing" Jews are actually of their father the Devil, as their deeds, even in context, clearly demonstrate. As an aside, this text clearly points out that if what we say we believe does not correspond to our deeds or behavior, we are deceiving ourselves and will had better carefully examine our profession of faith in Christ. And simply sitting in the pew on Sunday is not sufficient evidence of our deeds. Our deeds Monday through Saturday are a far better barometer of what we say we believe. Be careful to make certain that your practice does not belie your profession!)

The derivative word teknion (5040) designates a little child and was used for example by the apostle John (7 of 9 uses of teknion are in 1John written somewhere around 85-90AD possibly from Ephesus) to address the followers of Jesus, who must have seemed like very little ones to the aged apostle.

In Matthew 23 Jesus uses teknon in a "Hebraistic" sense to refer to the inhabitant of Jerusalem as if she were their mother, declaring...

"O Jerusalem, Jerusalem, who kills the prophets and stones those who are sent to her! How often I wanted to gather your children together, the way a hen gathers her chicks under her wings, and you were unwilling." (Mt 23:37)

In other Hebraistic uses teknon describes a person as characterized by some condition or quality -- "children of light" (see note Ephesians 5:8), "as obedient children" (Greek reads literally "children of obedience" see note 1 Peter 1:14), "accursed children" (more literally "children of a curse", see note 2 Peter 2:14)

In summary, in the present usage of teknon, Paul is referring to literal children as those born of their parents. In context of his discussion of the relationships in which one lives out the reality of a Spirit filled life, it appears that these children are best considered as believers.

J Vernon McGee tells the story of...

When I was a pastor, I remember visiting in a home in which the father and I couldn’t even carry on a conversation because his little boy occupied the center ring of the circus. He was a little circus himself, and if you ask me, the dear little fellow was a brat. The father said, “I just can’t make that child obey me.” The father weighed about two hundred pounds, and the boy weighed about thirty pounds. Yet the father said, “I just can’t make him obey me.” Well, I think he could have, and I think he should have. God intended for the father to make him obey at that age. (McGee, J V: Thru the Bible Commentary:  Thomas Nelson)

Obey (5219) (hupakouo from hupó = agency or means, under + akoúo  physical hearing and apprehension of something with the mind - akouo gives us our English acoustics - the science of design which helps one hear) (Click also the word study on the related noun hupakoe) literally means to listen under with attentiveness and to respond positively to what is heard. The sense is that one understands and responds accordingly. Note that hupakouo implies an inward attitude of respect and honor, as well as external acts of obedience.  Obedience on the part of children consists in listening to the advice given by parents. In Genesis 22 Isaac's willingness to be offered as a sacrifice is a model of such submission.

Hupakouo is present imperative which is a command for children to obey as a lifestyle. In the present verse hupakouo means that Spirit filled children are to continually put themselves under the words and authority of their parents. They are to continual exhibit a readiness to hearken (give respectful attention, give heed to) to the parent's commands and instructions.

The basic picture is that of placing oneself under what has been heard and therefore submitting to and obeying what is heard.

Hughes adds that...

Obedience involves conscious listening. If you do not really listen, you cannot really obey. That is why parents are always saying, “Listen to me!” The idea is to listen under with the intent to understand and do it... Much of this is a matter of attitude. We are not to be like the little boy who misbehaved and was told by his teacher to sit in the corner, which he did with grudging obedience, all the while saying to himself, “I’m sitting down on the outside, but I’m standing up on the inside!”  (Hughes, R. K.: Ephesians: The Mystery of the Body of Christ. Crossway Books)

It means to hear under authority and pictures the one hearing as being under the authority of some one else. Hupakouo means to obey on the basis of having paid attention to.

Thayer's first entry states that "properly, of one who on a knock at the door comes to listen who it is" In secular Greek the word spoke of one standing at a door, listening intently, almost eavesdropping. Such was the reference in the writings of Plato, who used the word to describe a doorkeeper. Later on the word came to mean obedience, for after one hears and understands a command or request, he should obey it. (See this meaning in Acts 12:13)

In the context of family relationships, it is notable that the wife is not commanded to obey her husband, as children are to obey their parents and slaves their masters. In other words, a husband is to treat his wife as an equal and not as his servant or as if she were a child.  The husband is not to order the wife about, calling on her to respond to his every wish and command.

Faith and obedience are closely related, C H Spurgeon writing that...

Faith and obedience are bound up in the same bundle. He that obeys God, trusts God; and he that trusts God, obeys God.

If you desire Christ for a perpetual guest, give him all the keys of your heart; let not one cabinet be locked up from him; give him the range of every room and the key of every chamber.

There are at least four NT uses of hupakouo that relate to the gospel and salvation  - Acts 6:7, Ro 6:17, Ro 10:16 , 2Thess 1:8 and Hebrews 5:9 (See these verses below). These uses of hupakouo are closely related to the phrase "obedience of faith" Dr Charles Ryrie summarizing the two main ways one might interpret this phrase explaining that it could refer to...

Study (in context) the 21 NT uses of hupakouo...

Matthew 8:27 And the men marveled, saying, "What kind of a man is this, that even the winds and the sea obey Him?"

Mark 1:27 And they were all amazed, so that they debated among themselves, saying, "What is this? A new teaching with authority! He commands even the unclean spirits, and they obey Him."

Mark 4:41 And they became very much afraid and said to one another, "Who then is this, that even the wind and the sea obey Him?"

Luke 8:25 And He said to them, "Where is your faith?" And they were fearful and amazed, saying to one another, "Who then is this, that He commands even the winds and the water, and they obey Him?"

Luke 17:6 And the Lord said, "If you had faith like a mustard seed, you would say to this mulberry tree, 'Be uprooted and be planted in the sea'; and it would obey you.

Acts 6:7 And the word of God kept on spreading; and the number of the disciples continued to increase greatlhy in Jerusalem, and a great many of the priests were becoming obedient to the faith.

Acts 12:13 And when he knocked at the door of the gate, a servant-girl named Rhoda came to answer (to hearken).

Romans 6:12 (note) Therefore do not let sin reign in your mortal body that you should obey its lusts...6:16  Do you not know that when you present yourselves to someone as slaves for obedience (hupakoe), you are slaves of the one whom you obey (hupakouo), either of sin resulting in death, or of obedience (hupakoe) resulting in righteousness? 6:17 But thanks be to God that though you were slaves of sin, you became obedient from the heart to that form of teaching to which you were committed. (Comment: In this context hupakouo is referring to yielding to one's the strong desires that are "barked out" by the Sin nature that still resides in believers. Paul's point is that now we do not have to obey those strong desires).

Romans 10:16 (note)  However, they did not all heed the glad tidings; for Isaiah says, "LORD, who has believed our report?"

Ephesians 6:1 Children, obey your parents in the Lord, for this is right...6:5 (note) Slaves, be obedient to those who are your masters according to the flesh, with fear and trembling, in the sincerity of your heart, as to Christ;

Philippians 2:12 (note)  So then, my beloved, just as you have always obeyed, not as in my presence only, but now much more in my absence, work out your salvation with fear and trembling;

Colossians 3:20 (note)  Children, be obedient to your parents in all things, for this is well-pleasing to the Lord...3:22 (note) Slaves, in all things obey those who are your masters on earth, not with external service, as those who merely please men, but with sincerity of heart, fearing the Lord.

2 Thessalonians 1:8 dealing out retribution to those who do not know God and to those who do not obey the gospel of our Lord Jesus.

2 Thessalonians 3:14 And if anyone does not obey our instruction in this letter, take special note of that man and do not associate with him, so that he may be put to shame.

Hebrews 5:9 And having been made perfect, He became to all those who obey Him the source of eternal salvation,

Hebrews 11:8 By faith Abraham, when he was called, obeyed by going out to a place which he was to receive for an inheritance; and he went out, not knowing where he was going.

1Peter 3:6 Thus Sarah obeyed Abraham, calling him lord, and you have become her children if you do what is right without being frightened by any fear.

Puritan Thomas Adams wrote that...

True obedience hath no lead at its heels

It is not what we do that matters, but what a sovereign God chooses to do through us. God doesn’t want our success; he wants us. He doesn’t demand our achievements; he demands our obedience.

Corrie Ten Boom once said that

When we are obedient, God guides our steps and our stops.

Elisabeth Elliot also emphasized the importance of obedience when she wrote

"Throughout the Bible ... when God asked a man to do something, methods, means, materials, and specific directions were always provided. The man had one thing to do: obey."

Trust and Obey
Play hymn

John H Sammis

When we walk with the Lord in the light of His Word,
What a glory He sheds on our way!
While we do His good will, He abides with us still
And with all who will trust and obey

Refrain
Trust and obey, for there's no other way
To be happy in Jesus but to trust and obey.

Not a burden we bear, not a sorrow we share,
But our toil He doth richly repay;
Not a grief or a loss, not a frown or a cross,
But is blessed if we trust and obey.

Refrain

But we never can prove the delights of His love
Until all on the altar we lay;
For the favor He shows, for the joy He bestows,
Are for them who will trust and obey.

Refrain

Then in fellowship sweet we will sit at His feet.
Or we’ll walk by His side in the way.
What He says we will do, where He sends we will go;
Never fear, only trust and obey.

Parents (1118) (goneus from ginomai = to generate) describes either the mother or father. Goneus is in the plural in this verse which would signify both parents.

In the Lord - A few Greek manuscripts omit this phrase, but the bulk of evidence supports its validity. Paul's point is that this prescribed obedience to parents is the child's obligation to Christ whether or not the parents are believers. "In the Lord" defines the quality of the obedience by defining the sphere in which that obedience is to be carried out. It is to be the obedience of a Spirit filled child in communion or fellowship with Christ and their obedience should be as if to Him, as if obeying the Lord Himself. Children are not commanded to obey their parents if their parents tell them to disobey the Lord. The principle is the same stated by Peter who declared

"We must obey God rather than men." (Acts 5:29)

Our Lord is also the example of obedience, Luke recording that...

He (Jesus as a boy) went down with them, and came to Nazareth; and He continued in subjection to (hupotasso) them; and His mother treasured all these things in her heart. (Luke 2:51)

Children are not simply to follow the example of Jesus when He subjected Himself to His parents, but must also realize that both they and their parents are under the authority of the living Christ.

The writer of Hebrews adds that...

Although He was a Son, He learned obedience from the things which He suffered. (See note Hebrews 5:8)

John Eadie writes that in the Lord describes...

the element or sphere of that obedience which children are to render to their parents, and certainly do not qualify goneus—as if the reference were to fathers in the faith, in contrast to fathers after the flesh. Not merely natural instinct, but religious motive should prompt children to obedience, and guard them in it. The love which Jesus showed to children, when He took them in His arms and blessed them, should induce them, in a spirit of filial faith and fondness, to obey their parents, and to regard with special sacredness every parental injunction. And that obedience, if prompted, regulated, and bounded by a sense of religious obligation, will be cheerful, and not sullen; prompt, and not dilatory; uniform, and not occasional; universal, and not capricious in its choice of parental precepts. (John Eadie, D., LL.D. The Epistle of St Paul to the Ephesians)

Blaikie writes that in the Lord...

qualifies, not “parents,” but “obey,” and indicates that the element or life which even children lead in fellowship with Christ makes such obedience more easy and more graceful. (The Pulpit Commentary: New Testament; Old Testament; Ages Software)

Salmond writes that in the Lord means...

“The sphere in which it is to move, a Christian obedience fulfilled in communion with Christ”

Expositors Greek  NT says this phrase

“defines the quality of the obedience by defining the sphere within which it is to move—a Christian obedience fulfilled in communion with Christ. (Nicoll, W Robertson, Editor: Expositors Greek Testament: 5 Volumes. Out of print. Search Google)

Vincent adds that the idea is that...

 The children being with their parents in the Lord, are to be influenced by religious duty as well as by natural affection. (Vincent, M. R. Word Studies in the New Testament 3:403)

FOR THIS IS RIGHT: touto gar estin (3SPAI) dikaion: (Nehemiah 9:13; Job 33:27; Psalms 19:8; 119:75,128; Hosea 14:9; Romans 7:12; 12:2; 1 Timothy 5:4) 

For this is right - right not just in the sense of befitting but in that it is righteous or what is defined by law as proclaimed in the Divine commandment.  It is the proper course to follow in an orderly society. This is God's righteous design, His template for a family life of order rather than disorder and even utter chaos. Therefore, it should not be surprising to discover that virtually every culture and society recognizes and is built upon the premise that children are to respect and obey their parents. There is an order in nature, ordained of God, that argues for the rightness of an action.

Warren Wiersbe quips that...

The “modern version” of Ephesians 6:1 would be, “Parents, obey your children, for this will keep them happy and bring peace to the home.” But this is contrary to God’s order in nature. (Wiersbe, W: Bible Exposition Commentary. 1989. Victor)

Hosea writes...

Whoever is wise, let him understand these things; Whoever is discerning, let him know them. For the ways of the LORD are right, And the righteous (Lxx = dikaios) will walk in them, but transgressors will stumble in them. (Hosea 14:9)

David adds that ...

The precepts of the LORD are right, rejoicing the heart; The commandment of the LORD is pure, enlightening the eyes. (Psalms 19:8)

Paul writes...

So then, the Law is holy, and the commandment is holy and righteous (right - dikaios) and good. (See note Romans 7:12)

Right (1342) (dikaios from dike = originally manner or tendency then coming to mean the designation for the right of established custom or usage. Dike is an expected behavior or conformity, not according to one's own standard, but according to an imposed standard.) describes that which is in accordance with what God requires and so is in accordance with His compelling standards. In man to man relations dikaios describes a right relationship, here of parent to child, where the child's hearkening to the parent is the essence of godly parent-child relationship.

Vine has this note on dikaios noting that it was...

first used of persons observant of dike, custom, rule, right, especially in the fulfilment of duties towards gods and men, and of things that were in accordance with right. The English word “righteous” was formerly spelt ‘rightwise’, i.e., (in a) straight way. In the N.T. it denotes righteous, a state of being right, or right conduct, judged whether by the Divine standard, or according to human standards, of what is right. Said of God, it designates the perfect agreement between His nature and His acts (in which He is the standard for all men).

J Vernon McGee notes that...

It is right because it is according to the will of God. It is actually more than right; it is just. It is a righteous thing to do because it is God’s way. The first lesson that a soldier must learn is obedience to those in authority. He must follow orders. This basic training is learned in the home. After the soldier has learned to obey, then he is in a position to be promoted to the rank of an officer where he gives commands to others. To know how to give orders depends largely on how the soldier learned to obey. This basic training is found in the home with the parent-child relationship, and then with the master-servant  relationship. The victories of the Christian life are won in the home and in the place of business. (McGee, J V: Thru the Bible Commentary:  Thomas Nelson)
