Conviction (1650) elegchos
Conviction (1650) (elegchos from elegcho = bringing to the light, to expose, to convict [Jn 3:20, Ep 5:11, 13], to convict) strictly speaking is a "bringing to the light." Elegchos indicates an inner conviction that is not based on visible matters. In this passage the believer is convinced that the things he or she is unable to see are real.
Elegchos is translated variously: "proof" (HCSB, Wuest), "evidence" (Geneva, Wesley), "to be certain" (TEV), "being certain" (Phillips), "prove the existence" (NJB), "certain" (NIV), "being convinced of" (NET), "persuasion" (Mace NT), "convinces us" (GWT), "the putting to the proof" (Centenary Translation of the NT), "the proof of the reality of the things" ( Williams)
Aristotle wrote that
Elegchos is the proof that a thing cannot be otherwise than we say.
A T Robertson on elegchos...
Old and common word from elegchÃ
 (Mt 18:15) for “proof” and then for “conviction.” Both uses occur in the papyri and either makes sense here, perhaps “conviction” suiting better though not in the older Greek.
Wuest adds...
The word “evidence” is the translation of elegchos which means, “a proof, that by which a thing is proved or tested.” Thayer in commenting on its use here defines it as follows: “that by which invisible things are proved and we are convinced of their reality.” His second definition of the word is “conviction.”
Vincent on elegchos...
Quite often in LXX for ÒøÃâÃ·Ã½× to reprove, rebuke, punish, blame. See Pr. 1:23; Wisd 2:14; Sir. 16:12. See especially on the kindred verb elegcho, John 3:20. Rend. conviction. Observe that hupostasis and elegchos are not two distinct and independent conceptions, in which case kai (and) would have been added; but they stand in apposition. Elegchos is really included in hupostasis, but adds to the simple idea of assurance a suggestion of influences operating to produce conviction which carry the force of demonstration. The word often signifies a process of proof or demonstration. So yon Soden: “a being convinced. Therefore not a rash, feebly-grounded hypothesis, a dream of hope, the child of a wish.”
Leon Morris writes that the exact meaning of elegchos in the present context is somewhat ambiguous for it...
usually signifies a “proof” or “test.” It may be used as a legal term with a meaning like “cross examining” (Liddell-Scott). Some take it here as “test” and some see its legal use, while many prefer to understand it in much the same sense as the preceding expression (e.g., NIV "certain of what we do not see"). This may well be the right way to take it, though “test” is far from impossible. The meaning would then be that faith, in addition to being the basis of all that we hope for, is that by which we test things unseen. We have no material way of assessing the significance of the immaterial. But Christians are not helpless. They have faith and by this they test all things.
Gromacki writes that elegchos describes...
the inner conviction of the heart whereby one knows that God, heaven, hell, sin, and forgiveness are just as real as rocks and trees. Biblical faith fosters this intrinsic certainty. (Gromacki — Stand Bold in Grace: An Exposition of Hebrews)
P E Hughes comments that elegchos conveys the idea...
Though the blessings promised are not yet revealed, the man of faith is convinced of their reality...the "conviction" of this phrase has a dynamic quality. It is not a static emotion of complacency but something lively and active, not just a state of immovable dogmatism but a vital certainty which impels the believer to stretch out his hand, as it were, and lay hold of those realities on which his hope is fixed and which, though unseen, are already his in Christ. In striking contrast to the man whose values are entirely those of this present world, the Christian is animated by the conviction that it is the very things which are not (yet) seen, those things which he appropriates by faith, that are real and permanent; he walks by faith, not sight (2Cor 4:18-note; 2Cor 5:7-note). (A Commentary On The Epistle To The Hebrews)
BDAG gives three basic meanings of elegchos...
(1) the act of presenting evidence for the truth of something... (Here in Hebrews 11:1) faith is a proving (or conviction about) unseen things = faith means to be sure about things unseen (in contrast to confidence in the temporal)
(2) the act of charging a person with wrongdoing (Lxx of Hab 2:1)
(3) expression of strong disapproval, reproof, censure, correction (Lxx of Job 6:26, variant reading of NA26 of 2Ti 3:16).
Elegchos is used only here in the NT if one examines the Nestle-Aland Greek Text. However the Textus Receptus (used for the KJV) and a variant reading of the Nestle-Aland uses elegchos in 2Ti 3:16 describing Scripture as profitable for "reproof."
Conviction is a firmly held belief which implies a deeper manifestation of the inward assurance. People of faith are prepared to live out their belief. If you believe truth, your behavior should manifest your belief. In other words, our lives should reflect a commitment to what our minds and hearts are assured is true. We should be so sure of God's promises and blessings which are future that we behave as if those promises were already realized (see Heb 11:7, 8, 9, 10, 11, 12, 13; cf. Ro 4:17, 18, 19, 20, 21).
Wiersbe adds that elegchos...
is the inward conviction from God that what He has promised, He will perform. The presence of God-given faith in one's heart is conviction enough that He will keep His Word. (Ibid)
As Butler emphasizes that...
Those who walk by faith in the Word of God will be people of conviction. Not surprisingly, unbelief, which walks in uncertainly, mocks conviction, telling us we cannot know for certain, etc. (Analytical Bible Expositor — Hebrews to Revelation)
F F Bruce adds that...
Physical eyesight produces conviction or evidence of visible things; faith is the organ which enables people (like Moses in Heb 11:27) to see the invisible order. (The New International Commentary on the New Testament — The Epistle to the Hebrews)
Vincent has a lengthy discussion of the meaning of the root verb elegcho explaining that it
has several phases of meaning. In earlier classical Greek it signifies to disgrace or put to shame. Thus Ulysses, having succeeded in the trial of the bow, says to Telemachus, “the stranger who sits in thy halls disgraces (elegchei) thee not” (“Odyssey, xxi., 424). Then, to cross-examine or question, for the purpose of convincing, convicting, or refuting; to censure, accuse. So Herodotus: “In his reply Alexander became confused, and diverged from the truth, whereon the slaves interposed, confuted his statements (elegchon, cross-questioned and caught him in falsehood), and told the whole history of the crime” (1:115). The messenger in the “Antigone” of Sophocles, describing the consternation of the watchmen at finding Polynices’ body buried, says: “Evil words were bandied among them, guard accusing (elegchon) guard” (260). Of arguments, to bring to the proof; prove; prove by a chain of reasoning. It occurs in Pindar in the general sense of to conquer or surpass. “Having descended into the naked race they surpassed (elegzan) the Grecian band in speed (“Pythia,” xi., 75). (Bolding added. Vincent, M. R. Word studies in the New Testament. Vol. 2, Page 1-102)
Elegchos - 11x in the non-apocryphal Septuagint - Lev 19:17; Nu 5:18, 19, 23, 24, 27; 2 Kgs 19:3; Ps 38:14; 39:11; 149:7; Isa 37:3. Most of these uses are to convey the idea of reproof (BDAG meaning #3 above).
Albert Barnes on elegchos...
It means, properly, proof, or means of proving, to wit, evidence; then proof which convinces another of error or guilt; then vindication or defense; then summary or contents. The idea of evidence which goes to demonstrate the thing under consideration, or which is adapted to produce conviction in the mind, seems to be the elementary idea in the word. So when a proposition is demonstrated; when a man is arraigned, and evidence is furnished of his guilt, or when he establishes his innocence; or when one by argument refutes his adversaries, the idea of convincing argument enters into the use of the word in each case. This, I think, is clearly the meaning of the word here.
"Faith in the Divine declarations answers all the purposes of a convincing argument, or is itself a convincing argument to the mind, of the real existence of those things which are not seen." But is it a good argument? Is it rational to rely on such a means of being convinced? Is mere faith a consideration which should ever convince a rational mind? The infidel says no; and we know there may be a faith which is no argument of the truth of what is believed. But when a man who has never seen it believes that there is such a place as London, his belief in the numerous testimonies respecting it which he has heard and read is, to his mind, a good and rational proof of its existence, and he would act on that belief without hesitation. When a son credits the declaration or the promise of a father who has never deceived him, and acts as though that declaration and promise were true, his faith is to him a ground of conviction and of action, and he will act as if these things were so. In like manner the Christian believes what God says. He has never seen heaven; he has never seen an angel; he has never seen the Redeemer; he has never seen a body raised from the grave; but he has evidence which is satisfactory to his mind that God has spoken on these subjects, and his very nature prompts him to confide in the declarations of his Creator. Those declarations are, to his mind, more convincing proof than anything else would be. They are more conclusive evidence than would be the deductions on his own reason; far better and more rational than all the reasonings and declarations of the infidel to the contrary. He feels and acts, therefore, as if these things were so-for his faith in the declarations of God has convinced him that they are so. The object of the apostle, in this chapter, is not to illustrate the nature of what is called saving faith, but to show the power of unwavering confidence in God in sustaining the soul, especially in times of trial; and particularly in leading us to act, in view of promises and of things not seen, as if they were so. "Saving faith" is the same kind of confidence directed to the Messiah-the Lord Jesus-as the Saviour of the soul. Notes on the New Testament Explanatory and Practical.
Brian Bell on the phrase "faith is the...conviction of things not seen"...
Faith is learning to live by insight rather than by sight....“For we walk by faith, not by sight.” (2Cor 5:7) Some see faith contrasted by sight, or contrasted with empirical evidence (something based on experiment or experience). We have a saying, “Seeing is what?...believing!” Don’t see faith as the opposite of sight, or in contrast to it. Then what’s he saying here? It is dealing with future issues! — What we have seen in the past gives us faith to believe in the future, though we haven’t seen it.. Example: How visible was God to the children of Israel? God showed Himself visible through: “the 10 plagues, the parting of the red Sea, the drowning of Pharaoh’s men, the manna, earth opening, the shining face of Moses, etc.” Now, all that happened yesterday!...Now, here’s what’s going to happen tomorrow! — “You will posses the land, it will be flowing with milk & honey, it will be your inheritance, etc.” I know you saw giants but have faith! Could any Jew see tomorrow, look into the future? Can you? Now we are confident these things WILL come to pass, because we have faith, we trust God, & we trust God will honor His word! “So, true biblical faith is believing what has already been shown in the past; which causes us to have faith in His future promises, though we haven’t seen them yet!”...Faith is confidence in God that leads to obedience to God. As seen in the rest of the chapter! To illustrate true faith, the writer points to some Old & New testament believers, showing how they trusted God to bless, provide, protect, lead, conquer, & give lifeââ¬Â¦even in the most dire circumstances. (Hebrews:11:1-7 Sermon Notes)
Augustine asked "What is faith, unless it is to believe what you do not see?"
Not seen - "Not" is Greek word "ou" signifying absolute negation. Faith has absolutely not yet seen what it will one day possess (Jesus, His Kingdom, etc).
Holman New Testament Commentary
Eyesight produces a conviction about objects in the physical world. Faith produces the same convictions for the invisible order.
