Acts 2:37

This is the conclusion which the apostle infers from the premises, applying what he had said very close and home, or it would not in all likelihood have had so good an effect. ye are the men. over all the creatures, beyond what the first Adam was; and Christ, King over all the people of God, to rule in them, and reign for them; for to this purpose he was the Christ, or the Anointed of God, declared by God to be so, and owned for such by all that believed in him.

They had compunction in their heart, with sorrow for their sins, especially against their Messias. (Witham)

I. They were startled, and convinced, and put upon a serious enquiry, v. 37. When they heard, or having heard, having patiently heard Peter out, and not given him the interruption they had been used to give to Christ in his discourses (this was one good point gained, that they were become attentive to the word), they were pricked to the heart, or in the heart, and, under a deep concern and perplexity, applied themselves to the preachers with this question, What shall we do? It was very strange that such impressions should be made upon such hard hearts all of a sudden. They were Jews, bred up in the opinion of the sufficiency of their religion to save them, had lately seen this Jesus crucified in weakness and disgrace, and were told by their rulers that he was a deceiver. Peter had charged them with having a hand, a wicked hand, in his death, which was likely to have exasperated them against him; yet, when they heard this plain scriptural sermon, they were much affected with it.

Verses 37-41 From the first delivery of that Divine message, it appeared that there was Divine power going with it; and thousands were brought to the obedience of faith. But neither Peter's words, nor the miracle they witnessed, could have produced such effects, had not the Holy Spirit been given. Sinners, when their eyes are opened, cannot but be pricked to the heart for sin, cannot but feel an inward uneasiness. The apostle exhorted them to repent of their sins, and openly to avow their belief in Jesus as the Messiah, by being baptized in his name. Thus professing their faith in Him, they would receive remission of their sins, and partake of the gifts and graces of the Holy Spirit. To separate from wicked people, is the only way to save ourselves from them. Those who repent of their sins, and give up themselves to Jesus Christ, must prove their sincerity by breaking off from the wicked. We must save ourselves from them; which denotes avoiding them with dread and holy fear. By God's grace three thousand persons accepted the gospel invitation. There can be no doubt that the gift of the Holy Ghost, which they all received, and from which no true believer has ever been shut out, was that Spirit of adoption, that converting, guiding, sanctifying grace, which is bestowed upon all the members of the family of our heavenly Father. Repentance and remission of sins are still preached to the chief of sinners, in the Redeemer's name; still the Holy Spirit seals the blessing on the believer's heart; still the encouraging promises are to us and our children; and still the blessings are offered to all that are afar off.
