Jesus is the author and perfector of our faith and if that isn't God given faith then what in tarnation is it, huh?
The passage is about
Faith meaning that the Lord, Jesus Christ, is the complete and perfect example of faith rather than that Jesus injects faith into each individual who comes to believe the gospel. Let's see what the passage says just to make sure that it is not being misinterpreted.
Hebrews 12:1-17 Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us, 2 Looking unto Jesus the author and finisher of [our] faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
3 For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds. 4 Ye have not yet resisted unto blood, striving against sin. 5 And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him: 6 For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. 7 If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? 8 But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons. 9 Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live? 10 For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness. 11 Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby. 12 Wherefore lift up the hands which hang down, and the feeble knees; 13 And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed. 14 Follow peace with all men, and holiness, without which no man shall see the Lord: 15 Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled; 16 Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright. 17 For ye know how that afterward, when he would have inherited the blessing, he was rejected: for he found no place of repentance, though he sought it carefully with tears.
And let's see what commentators say about verse 2.
Barnes Notes on The Bible
Looking unto Jesus - As a further inducement to do this, the apostle exhorts us to look to the Saviour. We are to look to his holy life; to his patience and perseverance in trials; to what he endured in order to obtain the crown, and to his final success and triumph.
The author and finisher of our faith - The word “our” is not in the original here, and obscures the sense. The meaning is, he is the first and the last as an example of faith or of confidence in God - occupying in this, as in all other things, the pre-eminence, and being the most complete model that can be placed before us. The apostle had not enumerated him among those who had been distinguished for their faith, but he now refers to him as above them all; as a case that deserved to stand by itself. It is probable that there is a continuance here of the allusion to the Grecian games which the apostle had commenced in the previous verse. The word “author” - ἀρχηγὸν archegon - (marg. beginner) - means properly the source, or cause of anything; or one who makes a beginning. It is rendered in Act 3:15; Act 5:31, “Prince”; in Heb 2:10, “Captain”; and in the place before us, “Author.”
It does not occur elsewhere in the New Testament. The phrase “the beginner of faith,” or the leader on of faith, would express the idea. He is at the head of all those who have furnished an example of confidence in God, for he was himself the most illustrious instance of it. The expression, then, does not mean properly that he produces faith in us, or that we believe because he causes us to believe - whatever may be the truth about that - but that he stands at the head as the most eminent example that can be referred to on the subject of faith. We are exhorted to look to him, as if at the Grecian games there was one who stood before the racer who had previously carried away every palm of victory; who had always been triumphant, and with whom there was no one who could be compared. The word “finisher” - τελειωτὴν teleioten - corresponds in meaning with the word “author.” It means that he is the completer as well as the beginner; the last as well as the first.
As there has been no one hitherto who could be compared with him, so there will be no one hereafter; compare Rev 1:8, Rev 1:11. “I am Alpha and Omega, the beginning and the ending, the first and the last.” The word does not mean that he was the “finisher” of faith in the sense that he makes our faith complete or perfects it - whatever may be true about that - but that he occupies this elevated position of being beyond comparison above all others. Alike in the commencement and the close, in the beginning of faith, and in its ending, he stands pre-eminent. To this illustrious model we should look - as a racer would on one who had been always so successful that he surpassed all competitors and rivals. If this be the meaning, then it is not properly explained, as it is commonly (see Bloomfield and Stuart in loc.), by saying that the word here is synonymous with “rewarder,” and refers to the βραβευτὴς brabeutes - or the distributor of the prize; compare notes on Col 3:15, There is no instance where the word is used in this sense in the New Testament (compare Passow), nor would such an interpretation present so beautiful and appropriate a thought as the one suggested above.
Cambridge Bible Commentary
Hebrews 12:2
looking unto Jesus] It is not possible to express in English the thought suggested by the Greek verb aphorôntes, which implies that we must “look away (from other things) unto Jesus.” It implies “the concentration of the wandering gaze into a single direction.”
the author] The word is the same (ἀρχηγὸν) as that used in Heb_2:10. In Act_3:15; Act_5:31 it is rendered “a Prince,” as in Isa_30:4 (LXX.). By His faithfulness (Heb_3:2) he became our captain and standard-bearer on the path of faith.
and finisher] He leads us to “the end of our faith,” which is the salvation of our souls (1Pe_1:9).
of our faith] Rather, “of faith.”
endured the cross, despising the shame] Lit., “endured a cross, despising shame.”
is set down] Rather, “hath sat down” (Heb_1:3, Heb_8:1, Heb_10:12).
The passage is not teaching that the Lord puts faith into people it is teaching that Jesus Christ is the example to which Christians must attentively behold so that they can follow his example.
