AND WE DESIRE THAT EACH ONE OF YOU SHOW THE SAME DILIGENCE: epithumoumen (1PPAI) de hekaston humon ten auten endeiknusthai (PMN) spouden: (Ro 12:8,11 1Co 15:58; Gal 6:9 Php 1:9-11; 3:15 1Th 4:10 2Th 3:13 2Pe 1:5-8; 3:14)

We desire (1937) Earnestly long for, have strong desire for (1Ti 3:1)

Lust (1937) (epithumeo from epí = upon, used intensively + thumós = passion) (Click for in depth study of related noun epithumia) means literally to fix the desire upon (whether things good or bad). It means to have a strong desire to do or secure something. Note that the preposition "epi" can  express motion toward! And so it means to have one's passions or affections directed toward something (good or bad).

That is, we desire (continually -
present tense) that each of you exhibit the same diligence to develop your hope, which is in danger of failing, into full assurance, unto the end of the present season of trial with its happy consummation....It is practically the same whether it is translated full development or full assurance. The two meanings coalesce. Hope develops into full assurance.

Each (
1538) (hekastos from hékas = separate) every single one. This idea of separation or singling out is expressed still more strongly by heís hékastos. It means each and every one of you. The writer gets very personal and does not want to leave anyone out.

Show (1731) (endeíknumi from preposition en = in, to + deíknumi = to show) means to point out, to demonstrate, to put on display, to prove, to show proof, to show forth, to show oneself, to give visible proof, to show in anything and implies an appeal to facts. The preposition (in) in the compound suggests more than the simplest demonstration. It is like laying the index finger, as it were, on the object. It means to to show something in someone. It can mean to do something to someone, as Alexander the coppersmith "did" (endeíknumi) Paul much harm (2 Timothy 4:14 note). In the papyri it could have a quasi-legal sense of proving a petition or charge or of proving that a charge was wrong. Josephus used endeíknumi to describe Herod Agrippa’s display of generosity to those of other nations (Josephus, Antiquities, 19:330).

The present tense calls for the saints to continually demonstrate this diligence demonstrated by the patriarchs (he illustrates this diligence with "father" Abraham - see notes Hebrews 6:13; 6:14; 6:15 ). The middle voice indicates that we ourselves must each consciously initiate this action (empowered by the Spirit of course) so that we continually show forth or demonstrate a zealous urgency. 

Diligence  (4710) (spoude from speudo = hasten, make haste) refers to eagerness, earnestness,  willingness or zeal. It denotes quick movement or haste accompanying the eagerness, etc, in the interest of a person or cause. Thus spoude can refer to swiftness of movement or action and means haste or speed (like our expression "in a hurry"). It can refer to an earnest commitment in discharge of an obligation or experience of a relationship.

Spoude was often used in Greek and Roman literature and found on inscriptions in reference to extraordinary commitment to civic and religious responsibilities, which were frequently intertwined, and also of concern for personal moral excellence or optimum devotion to the interests of others.

Spoude is primarily an attitude which leads to an action. Spoude means to do something with intense effort and motivation, with quick movement and is in opposition to the attitude of slothfulness. The individual who is "spoude" who is eager to do something and ready to expend the necessary energy and effort.

Spoude describes zeal (eagerness and ardent interest in pursuit of something), passion (passion applies to an emotion that is deeply stirring-- how wonderful to so fully be in love with Christ so as to be fully governed by His Spirit).

Note that assurance comes from diligence. If we are diligent in living for Christ, our hearts are filled with assurance. If we are not diligent, then we cannot be assured that all things will be well. Living an up and down life—sometimes living for Christ and other times not living for Christ, sometimes living in sin and sometimes living in righteousness—causes doubt, questioning, and wondering about salvation. And it should. We should fear lest we fall away from Christ and His Word.

F B Hole (Biographical Note) writes that...

Being thus assured of the salvation of the mass of those to whom he wrote, there is but one word of exhortation at this point. The writer urges them to go on doing as they had done — to continue diligently in this good way to the end, in the full assurance that their hope was not misplaced.

Hope has a very large place in connection with the faith of Christ, just as it had in the bygone dispensation. Then, whether patriarchs or prophets or just the people of God, they all had their eyes directed forward to the good things to come at the advent of the Messiah. Now the good things have been manifested in Christ — full atonement has been made, our consciences have been purged, we have received the gift of the Spirit. Yet even so we are not in the full enjoyment of the good things. For that we await the second coming of the Lord. What we actually have at the present moment we have in faith, and we enjoy by the power of the Spirit, for He is the Earnest of all we shall inherit. We are saved, in hope of all that is to come.

It is very important for us to be clear as to this, and even more important it was for these converted Hebrews to be clear as to it. How often did they get reproached by their unconverted relations! How often taunted with their folly in giving up all the outward glories of the Mosaic system with its temple, its altar, its sacrifices, its priesthood — and for what? For a Master whom they could not see, for He had left them, and for a whole range of things as invisible as He! What fools they appeared to be! But were they really fools?

They were not. And if instructed in that which our chapter says they would be able to give very good reason for what they had done. They would be able to say, "It is really we and not you who are following in the footsteps of our father Abraham. Promises were made to him and you seem to have forgotten them, settling down as though contented with the shadow system of the law, which was given through Moses as a provisional thing. We have received Christ, and in Him we have the pledge of the fulfilment of every promise which ever was given, and we have fresh, and even brighter promises besides."

We need to have a hope which is resting upon a very weld established basis if we are to hold it with full assurance. It is this thought which leads to verses 13-18. (Hebrews Commentary Notes)

Here is an incredible illustration of diligence...

The Proceedings of the U.S. Naval Institute: The USS Astoria (CA-34) was the first U.S. cruiser to engage the Japanese during the Battle of Savo Island, a night action fought 8-9 August 1942. Although she scored two hits on the Imperial flagship Chokai, the Astoria was badly damaged and sank shortly after noon, 9 August.

About 0200 hours a young midwesterner, Signalman 3rd Class Elgin Staples, was swept overboard by the blast when the Astoria's number one eight-inch gun turret exploded. Wounded in both legs by shrapnel and in semi-shock, he was kept afloat by a narrow lifebelt that he managed to activate with a simple trigger mechanism.

At around 0600 hours, Staples was rescued by a passing destroyer and returned to the Astoria, whose captain was attempting to save the cruiser by beaching her. The effort failed, and Staples, still wearing the same lifebelt, found himself back in the water. It was lunchtime. Picked up again, this time by the USS President Jackson (AP-37), he was one of 500 survivors of the battle who were evacuated to Noumea.

On board the transport Staples, for the first time, closely examined the lifebelt that had served him so well. It had been manufactured by Firestone Tire and Rubber Company of Akron, Ohio, and bore a registration number.

Given home leave, Staples told his story and asked his mother, who worked for Firestone, about the purpose of the number on the belt. She replied that the company insisted on personal responsibility for the war effort, and that the number was unique and assigned to only one inspector. Staples remembered everything about the lifebelt, and quoted the number. It was his mother's personal code and affixed to every item she was responsible for approving.

Fifty years ago, a mother's unheralded diligence in an anonymous wartime job assured her soon-to-be shipwrecked son's survival. But how much greater are the stakes in eternal matters, and how much greater is the challenge to diligence in eternal matters! "We want [literally, we long for] each one of you," says the writer in v11, "to show this same diligence to the very end, in order to make your hope sure."

SO AS TO REALIZE THE FULL ASSURANCE OF HOPE UNTIL THE END: pros ten plerophorian tes elpidos achri (until) telousn: (Heb 3:6,14; 10:22 Isa 32:17 Col 2:2 1Th 1:5 2Pe 1:10 1Jn 3:14,19) (Hope - Heb 6:18-20 Ro 5:2-5; 8:24,25; 12:12; 15:13 1Co 13:13 Gal 5:5 Col 1:5,23 2Th 2:16,17 1Pe 1:3-5,21 1Jn 3:1-3) (To the end - Heb 3:6,14; 10:32-35 Mt 24:13 Rev 2:26 )

See result of Abraham's faith and patience in  Romans 4:21 (see notes)

The expression full assurance is used three times in the NT.

(1) Full assurance of faith—we rest on God’s word, His testimony to us (see note Hebrews 10:22).

(2) Full assurance of understanding—we know and are assured (see note Colossians 2:2).

(3) Full assurance of hope—we press on with confidence as to the outcome (Hebrews 6:11).

How does one in fact "realize the full assurance of (the) hope"? It is thru faith and patience and so the writer gets very pragmatic, reminding his predominantly Jewish audience of one they would be very familiar with (Abraham) and in fact quoting directly from the Lxx of Ge 22:17, as probably the ultimate example of Abraham's faith...he had believed God in Ge 15:6 but God's call to sacrifice his son Isaac was the ultimate test of Abraham's faith (obedience) by which he became the father of all those who believe.

Only as we apply zeal and apply faith and patience can we have an assurance that we will one day "inherit the promises". Without them, we become sluggish, and as such expose ourselves to the danger of apostasy. This idea of applying diligence is very important if you desire to sense "spiritual security".  Peter describes this need for diligence (2Peter 1:5;  2Pe 1:10;  1:11 see notes
2Peter 1:5;  1:10;  1:11)

Note hope is modified by the definite article the (tes") in the Greek so this is a very specific hope, not some generalization or "pie in the sky by and by". This reflects the absolute certainty of future good, because as taught below Jesus has entered thru the veil and will be there as our High Priest forever. That is a sure & steadfast anchor for our souls when storms of life assail us, which are in fact guaranteed if we are truly His children (Philippians 1:29-
note, Jn 16:33)

Hope (1680) (elpis in Scripture is not the world's definition of "I hope so", with a few rare exceptions (e.g., Acts 27:20) but is is an absolute certainty of future good. Hope is defined as a desire for some future good with the expectation of obtaining it or as Peter Anderson put it "Hope is faith in the future tense." Hope is confident expectancy. Hope is the looking forward to something with some reason for confidence respecting fulfillment. See related study on the Believer's Blessed Hope.

I like John Blanchard's definition of the Christian's hope...

'Hope' is biblical shorthand for unconditional certainty.

Hope as the world typically defines it is a desire for some future occurrence of which one is not assured of attaining. The ancient world did not generally regard hope as a virtue, but merely as a temporary illusion. Historians tell us that a great cloud of hopelessness covered the ancient world. Philosophies were empty; traditions were disappearing; religions were powerless to help men face either life or death. People longed to pierce the veil and get some message of hope from the other side, but there is none outside of Christ.

it. In the OT there are several Hebrew words translated "hope" but each has the idea of inviting us to look ahead eagerly with confident expectation, the same idea conveyed by elpis. Each Hebrew word for "hope" calls for patience, reminding us that the fulfillment of our hope lies in the future ("hold on...the best is yet to come").

Hope is by no means a passive attitude but a stimulant to action for Thomas Brooks writes that...

A man full of hope will be full of action... Hope can see heaven through the thickest clouds.

John Calvin adds that...

When hope animates us there is a vigour in the whole body.

Hope is a repeated theme in Hebrews. Study the 5 uses in context...

Hebrews 3:6 (note) - but Christ was faithful as a Son over His house --whose house we are, if we hold fast our confidence and the boast of our hope firm until the end.

Hebrews 6:11 (note) - And we desire that each one of you show the same diligence so as to realize the full assurance of hope until the end,

Hebrews 6:18 (note) - so that by two unchangeable things in which it is impossible for God to lie, we who have taken refuge would have strong encouragement to take hold of the hope set before us.

Hebrews 7:19 (note) - (for the Law made nothing perfect ), and on the other hand there is a bringing in of a better hope, through which we draw near to God.

Hebrews 10:23 (note) - Let us hold fast the confession of our hope without wavering, for He who promised is faithful;

Gabriel Marcel said,

Hope is for the soul what breathing is for the living organism.”

A study of concentration camp survivors found that those prisoners who were able to hold onto their sense of hope (‘things are going to get better’ or ‘we’re going to get out of here one day’ ) were much more likely to survive. Hope then is not optional but for these prisoners proved to be a matter of life and death.

Vincent writes that hope

"in classical Greek, has the general signification of expectancy, relating to evil as well as to good. Thus Plato speaks of living in evil hope (“Republic,” i., 330); i.e., in the apprehension of evil; and Thucydides, of the hope of evils to come; i.e., the expectation or apprehension.  In the New Testament the word always relates to a future good." (Vincent, M. R. Word Studies in the New Testament Vol. 1)

Seneca, Rome's leading intellectual figure, tutor of the depraved emperor Nero (who forced Seneca to commit suicide!) and contemporary of Paul tragically defined hope as “an uncertain good”, the antithesis of Biblical hope! What a difference the new birth in Christ makes in one's perspective.

The cynical editor H. L. Mencken also inaccurately defined hope as

“a pathological belief in the occurrence of the impossible.”

His cynical definition does not even agree with the secular Webster's Collegiate dictionary which defines "Hope" much like the NT declaring that hope means "to cherish a desire with anticipation, desire with expectation of obtainment, expect with confidence."

Biblical hope is not "finger crossing", but is alive and certain because of the resurrection of Jesus Christ from the dead. Life without Christ is a hopeless end whereas life in Christ is an endless hope.

The book of Hebrews defines hope as that which gives "full assurance" (see note Hebrews 6:11). Thus we can have strong confidence that God is going to do good to us in future. The opposite of hope is despair, (hopelessness; a hopeless state; a destitution of hope or expectation) which is all that those without Christ as Savior can know, for Paul defines hope as "Christ Jesus, Who is our Hope" (1Ti 1:1). Thus genuine Biblical hope is not a concept but a Person, Christ Jesus!

Jeremiah pleaded with God on the basis of His Name, "Hope of Israel" (God's Names all reveal some aspect or attribute of His character), declaring

"Thou Hope of Israel, its Savior in time of distress. Why art Thou like a stranger in the land Or like a traveler who has pitched his tent for the night?" (Jer14:8)

Again Jeremiah says

"O LORD, the hope of Israel, all who forsake Thee will be put to shame. Those who turn away on earth will be written down, because they have forsaken the fountain of living water, even the LORD." (Jer 17:13)

The psalmist declares

"Thou art my hope; O Lord GOD, Thou art my confidence from my youth." (Ps 71:5)

Paul uses makes an allusion to this OT name ("Hope of Israel") speaking to the Jews explaining that

"I requested to see you and to speak with you, for I am wearing this chain for the sake of the hope of Israel." (Acts 28:20)

Although the Old  revealed spoke of the Hope of Israel and predicted His coming to save His people as well as Gentiles, there was no mention that the Messiah of hope would actually live within each member of His redeemed church. Paul explained that in the New Covenant, "God willed to make known what is the riches of the glory of this mystery among the Gentiles, which is Christ in you, the hope of glory." (see note Colossians 1:27)  The unsaved are born into the world but have "no hope and (are) without God in the world" (Ephesians 2:12 note, 1Thes 4:13- note) and if they die without Christ, he will be hopeless forever.

The Italian poet, Dante, in his Divine Comedy, put this inscription over the world of the dead:

“Abandon all hope, you who enter here!”

In other words, life without Christ is a hopeless end whereas life in Christ is an endless hope.

Hope in Scripture is the absolute certainty of future good and believers are to be continually, actively, expectantly

"looking for the blessed hope and the appearing of the glory of our great God and Savior, Christ Jesus."  (see note Titus 2:13).

A living hope should motivate a "looking" hope, so that we are waiting anxiously for Christ's return at any time, this event providing great incentive to "discipline (one's self) for the purpose of godliness" (1Timothy 4:7-note) knowing that godliness "is profitable for all things, since it holds promise for the present life and also for the life to come." (1Timothy 4:8-note

G K Chesterton said that

"Hope means hoping when things are hopeless or it is no virtue at all...As long as matters are really hopeful, hope is mere flattery or platitude. It is only when everything is hopeless that hope begins to be a strength."

Hope is an essential and fundamental element of Christian life, so essential indeed, that, like faith and love, Peter refers to it in this verse to designate the essence of Christianity

Hope is one component of the great triad of Christian virtues, along with faith and love.

“But now abide faith, hope, love, these three; but the greatest of these is love” (1Cor 13:13; see note 1Thessalonians 1:3; 5:8; Gal 5:5, 6; see notes Ephesians 1:15 1:16; 1:17; 1:18, Ephesians 4:2; 4:3; 4:4; 4:5; Colossians 1:4; 1:5; Hebrews 10:22; 10:23; 10:24; 1 Peter 1:21; 1:22).

Faith and hope are inseparably linked. We believe and so we hope.

Paul prayed for believers

"that the eyes of (our) heart may be enlightened, so that (we) may know what is the hope of His calling." (see note Ephesians 1:18)

Hope is a "helmet of salvation" for we know that

God has not destined us for wrath but for obtaining salvation through our Lord Jesus Christ (see note 1Thessalonians 5:8).

Hope as you can see is a deep well, which is well worth lingering over if you have time. To renew your mind with this great Biblical truth go over the following Scriptures, asking what each teaches about the "source" of hope, the stabilizing effect of the truth, the sanctifying effect, etc. Then study the chart summary at the end of the references --   (Job 8:13; 27:8, Ps 31:24;  Ps 42:5-6; 71:5;  Ps 119:49-50;  Ps 130:7; Ps 146:5 Pr 10:28; 13:12  Jer 14:8; 29:11; Jn 5:45 Acts 2:26; Acts 23:6, 24:15; 26:6; 28:20; Ro 4:18; 5:1-2; 8:25; 12:12; 15:4; 15:13 1Co 13:13; 15:19, 21-23 2Cor 3:12 Eph 1:15-18, 2:12; 4:2-5;  Gal 5:5, 6 Col 1:4, 5, 1:27  1Th 1:3; 1Thes 2:19; 4:13-18; 1Thes 5:8; 2Thes 2:16; 1Tim 1:1; Titus 2:11-13; 3:7 Heb 6:11, Heb 6:18-20; 7:19; 10:22-24; 1Pet 1:3; 1:21–22, 1Pet 3:15; 1Jn 2:25; 1Jn 3:2-3 ; Jude 1:21)

End (5056) (telos) refers to the goal. It is used 5x in Hebrews...

Hebrews 3:6 (note) - but Christ was faithful as a Son over His house --whose house we are, if we hold fast our confidence and the boast of our hope firm until the end.

Hebrews 3:14 (note) - For we have become partakers of Christ, if we hold fast the beginning of our assurance firm until the end,

Hebrews 6:8 (note) - but if it yields thorns and thistles, it is worthless and close to being cursed, and it ends up being burned.

Hebrews 6:11 (note) - And we desire that each one of you show the same diligence so as to realize the full assurance of hope until the end,

Hebrews 7:3 (note) - Without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like the Son of God, he remains a priest perpetually.

A reliable sign of regeneration is a faith that does not fail and continues to the end of life. It may at times falter and grow dim as it faces various trials and pressures, but it cannot be wholly abandoned. One wag has observed,

“If your faith fizzles before you finish, it’s because it was faulty from the first!”

Ray Stedman writes...

I recall once receiving a phone call from a young new Christian who said, “I’ve decided to give up being a Christian; I can’t handle it anymore.” Knowing him well, I said, “I agree. That’s probably what you ought to do.” There was silence on the line for a moment, and then he said, “You know I can’t do that!” And I said, “No, I know you can’t.” And he couldn’t—and he didn’t!

 

Hebrews 6:12  so that you will not be sluggish, but imitators of those who through faith and patience inherit the promises.   (NASB: Lockman)

Greek: hina me nothroi genesthe, (2PAMS) mimetai de ton dia pisteos kai makrothumias kleronomounton (PAPMPG) tas epaggelias.
Amplified:
 In order that you may not grow disinterested and become [spiritual] sluggards, but imitators, behaving as do those who through faith (by their leaning of the entire personality on God in Christ in absolute trust and confidence in His power, wisdom, and goodness) and by practice of patient endurance and waiting are [now] inheriting the promises. (Amplified Bible - Lockman)
NLT: Then you will not become spiritually dull and indifferent. Instead, you will follow the example of those who are going to inherit God's promises because of their faith and patience. (NLT - Tyndale House)
Phillips: We do not want any of you to grow slack, but to follow the example of those who through sheer patient faith came to possess the promises. (
Phillips: Touchstone)
Wuest:in order that you may become not sluggish, but imitators of those who through faith and patience are now inheriting the promises. (
Erdmans
Young's Literal: that ye may not become slothful, but followers of those who through faith and patient endurance are inheriting the promises.

THAT YOU MAY NOT BE SLUGGISH BUT IMITATORS: hina me nothroi genesthe (2PAMS)  mimetai de: (Heb 5:11,  Pr 12:24, 13:4, 15:19, 18:9, 24:30-34, Mt 25:26, Ro 12:11, 2Pe 1:10 )

That you - Hina (2443) introduces a purpose clause. The purpose for his reader's diligence, zealousness and eagerness (discussed in the previous verse) is that they might not fall into the trap of "sloppy spirituality", becoming veritable spiritual sloths.

Peter gave a similar sobering charge to diligence...

Therefore, brethren, be all the more diligent (aorist active imperative = not a suggestion but a command to do this now! Do it effectively! Don't delay!) to make certain (bebaios) about His calling (klesis) and choosing you; for as long as you practice these things, you will never stumble (see note 2 Peter 1:10)

May not be (1096) (ginomai) means to become or come into existence in aorist tense or momentary tense can indicate a decisive act with consequent results. They were already dull of hearing. The writer's desire here is that they might not become dull in conduct!

Spiritual sluggishness is an ever present danger for all believers and a tendency we must fight against (enabled by the Spirit, cp Ezekiel 36:27 - note the "balance" in God's promise of the New Covenant in Ezekiel - first God's part, then our part!), for just as friction stops a train that lacks a consistent source of power so will each of us wind down (or burn out) without complete dependence on His power (see notes Philippians 4:13, 2 Timothy 2:1, Ephesians 6:10 cp Philippians 2:12; 2:13)

Sluggish (3576) (nothros from negative = no + ôtheô = to push means no push in the hearing) is literally "no push" and thus means slow, sluggish, "numbed" in mind as well as in the ears.  The idea is they are slow, slothful, slack, obtuse, languid, lazy, sluggish.

In NT nothros is found only here and Hebrews 5:11

Concerning him we ha
