He hath raised up his Son. He gathereth out of the words of Moses that Christ is now revealed. But the words do seem to import no such thing; yet doth he reason fitly thus, because the blessing could no otherwise be, unless the beginning thereof did flow from the Messias. For we must always remember this, that all mankind is accursed, and, therefore, there is a singular remedy promised us, which is performed by Christ alone. Wherefore, he is the only fountain and beginning of the blessing. And if so be that Christ came to this end, that he may bless the Jews first, and, secondly, us, he hath undoubtedly done that which was his duty to do; and we shall feel the force and effect of this duty in ourselves, unless our unbelief do hinder us. This was a part of the priest's office under the law, to bless the people; and, lest this should be only a vain ceremony, there was a promise added; as it is, (Numbers 6:27.) And that which was shadowed in the old priesthood was truly performed in Christ, (Hebrews 7:1, 6.) Concerning which matter we have spoken more at large in the seventh chapter to the Hebrews. I like not Erasmus's translation; for he saith, when he had raised him up, as if he spoke of a thing which was done long ago. But Peter meaneth rather, that Christ was raised up, when he was declared to be the author of the blessing; which thing, since it was done of late and suddenly, it ought to move their minds the more. For the Scripture useth to speak thus, as in the last place, of Moses, whereunto Peter alludeth. To raise up a prophet, is to furnish him with necessary gifts to fulfill his function, and, as it were, to prefer him to the degree of prophetical honor. And Christ was raised up then, when he fulfilled the function enjoined him by his Father, but the same thing is done daily when he is offered by the gospel, that he may excel amongst us. We have said that in the adverb of order, first, is noted the right of the first-be-gotten, because it was expedient that Christ should begin with the Jews, that he might afterward pass over unto the Gentiles. Whilst that he turneth. He doth again commend the doctrine of repentance, to the end we may learn to conclude under the blessing of Christ newness of life, as when Esaias promiseth that a "Redeemer should come to Zion," he addeth a restraint; [1] "Those which in Jacob shall be turned from their iniquities." For Christ doth not do away the sins of the faithful, to the end they may grant liberty to themselves to sin under this color; but he maketh them therewith all new men. Although we must diligently distinguish these two benefits which are linked together, that this ground-work may continue, that we are reconciled to God by free pardon, I know that other men turn it otherwise; but this is the true meaning of Luke; for he speaketh thus word for word, "In turning every one from his wickedness."

Footnotes

1 - "Restrictionem," a reservation.

Unto you first - To you who are Jews. This was the direction, that the gospel should be first preached to the Jews, beginning at Jerusalem, Luke 24:47. Jesus himself also confined his ministry entirely to the Jews.
Having raised up - This expression does not refer to his having raised him from the dead, but is used in the same sense as in Acts 3:22, where God promised that he would raise up a prophet, and send him to teach the people. Peter means that God had appointed his Son Jesus, or had commissioned him to go and preach to the people to turn them away from their sins.
To bless you - To make you happy; to fulfill the promise made to Abraham.
In turning away - That is, by his preaching, example, death, etc. The highest blessing that can be conferred upon people is to be turned from sin. Sin is the source of all woes, and if people are turned from that, they will be happy. Christ blesses no one in sin, or while loving sin, but by turning them from sin. This was the object which he had in view in coming, Isaiah 59:20; Matthew 1:21. The design of Peter in these remarks was to show them that the Messiah had come, and that now they might look for happiness, pardon, and mercy through him. As the Jews might, so may all; and as Jesus, while living, sought to turn away people from their sins, so he does still, and still designs to bless all nations by the gospel which he had himself preached, and to establish which he died. All may therefore come and be blessed; and all may rejoice in the prospect that these blessings will yet be bestowed on all the kindreds of the earth. May the happy day soon come!

Unto you first, God, having raised up - As you are the children of the prophets, and of the covenant, the first offers of salvation belong to you, and God thus makes them to you. The great mission of Jesus Christ is directed first to you, that you may be saved from your sins. God designs to bless you, but it is by turning each of you away from his iniquities. The salvation promised in the covenant is a salvation from Sin, not from the Romans; and no man can have his sin blotted out who does not turn away from it.
1. We may learn from this that neither political nor ecclesiastical privileges can benefit the soul, merely considered in themselves: a man may have Abraham for his father, according to the flesh; and have Satan for his father, according to the spirit. A man may be a member of the visible Church of Christ, without any title to the Church triumphant. In short, if a man be not turned away from his iniquities, even the death of Christ profits him nothing. His name shall be called Jesus, for he shall Save his people From their Sins.
2. If Christ be the substance and sum of all that the prophets have written, is it not the duty and interest of every Christian, in reading the Scriptures, to search for the testimony they bear to this Christ, and the salvation procured by his death?

Unto you first God, having (k) raised up his Son Jesus, sent him to bless you, in turning away every one of you from his iniquities.
(k) Given to the world, or raised from the dead, and advanced to his kingdom.

Unto you first, God having raised his Son Jesus,.... Which may be understood, either of the incarnation of Christ, and his exhibition in the flesh; which is sometimes expressed by raising him up, and is no other than the mission, or manifestation of him in human nature, as in Luke 1:69. Or of the resurrection of him from the dead, and the exaltation of him at the right hand of God:
sent him to bless you; in person, according to the former sense; for he was indeed sent only to the people of Israel, and to them he preached; many of whom were blessed with converting grace under his ministry; but according to the latter sense, and which seems most agreeable, he was sent in the ministry of the word, and came by his Spirit, first to the Jews, among whom the Gospel was first preached for a while, and was blessed to the conversion of many thousands among them, both in Judea, and in the nations of the world, where they were dispersed:
in turning away everyone of you from his iniquities; in this the blessing lay, and is rightly in our version ascribed to Christ, and to the power of his grace, in the ministration of the Gospel and not to themselves, as in many other versions; as the Syriac version, "if ye convert yourselves, and turn from your evils"; making it both their own act, and the condition of their being blessed; and the Arabic version likewise, "so that everyone of you departs from his wickedness"; but that work is Christ's, and this is the blessing of grace he himself bestows, and is a fruit of redemption by his blood, Titus 2:14.

God, having raised up--not from the dead, but having provided, prepared, and given.
his Son Jesus--"His Servant Jesus" (see on Acts 3:13).
sent him to bless you--literally, "sent Him blessing you," as if laden with blessing.
in turning away every one of you from his iniquities--that is, "Hitherto we have all been looking too much for a Messiah who should shed outward blessings upon the nation generally, and through it upon the world. But we have learned other things, and now announce to you that the great blessing with which Messiah has come laden is the turning away of every one of you from his iniquities." With what divine skill does the apostle, founding on resistless facts, here drive home to the conscience of his auditors their guilt in crucifying the Lord of Glory; then soothe their awakened minds by assurances of forgiveness on turning to the Lord, and a glorious future as soon as this shall come to pass, to terminate with the Personal Return of Christ from the heavens whither He has ascended; ending all with warnings, from their own Scriptures, to submit to Him if they would not perish, and calls to receive from Him the blessings of salvation.

Unto you first. To Israel first in order, before the Gentiles, but Peter here recognizes the fact that the Gospel is also for other races.
Sent him to bless you. Not in person, but by the preaching of Christ as the Savior from sin. The best of all blessings is "the turning of them from iniquity," as that brings all others.

To bless you, by turning you from your iniquities - Which is the great Gospel blessing.
