Acts 2:40

lest they should doubt of pardon and grace, their sin having been so great. St. Peter gives them a ground of hope, they being the descendants from Abraham, unto whom especially this was promised, Jer 31:34. that is, to the Gentiles as well as to the Jews, who were said to be a people near unto God, as the Gentiles were said to be afar off, Isa 57:19 Eph 2:13. vocation, whether external by the word only, or internal by the Spirit also, depends on the pleasure of God; but the same promises of pardon and acceptance upon repentance made unto the Jews, are as effectually to be trusted unto by any of the Gentiles, as by any formerly amongst the Jews.

And with a great many other words did he testify and exhort them. St. Luke only gives an abridgment of those exhortations, which St. Peter, and the apostles frequently gave to all the people. St. Peter, as St. Chrysostom observes, and as we see in these Acts, was the mouth of all the rest. And on this first day of Pentecost, about three thousand were converted. (Witham)

III. These directions are followed with a needful caution (v. 40): With many other words, to the same purport, did he testify gospel truths, and exhort to gospel duties; now that the word began to work he followed it; he had said much in a little (v. 38, 39), and that which, one would think, included all, and yet he had more to say. When we have heard those words which have done our souls good, we cannot but wish to hear more, to hear many more such words. Among other things he said (and it should seem inculcated it), Save yourselves from this untoward generation. Be you free from them. The unbelieving Jews were an untoward generation, perverse and obstinate; they walked contrary to God and man (1 Thess 2 15), wedded to sin and marked for ruin. Now as to them, 1. "Give diligence to save yourselves from their ruin, that you may not be involved in that, and may escape all those things" (as the Christians did): "Repent, and be baptized; and then you shall not be sharers in destruction with those with whom you have been sharers in sin." O gather not my soul with sinners. 2. "In order to this continue not with them in their sin, persist not with them in infidelity. Save yourselves, that is, separate yourselves, distinguish yourselves, from this untoward generation. Be not rebellious like this rebellious house; partake not with them in their sins, that you share not with them in their plagues." Note, To separate ourselves from wicked people is the only way to save ourselves from them; though we hereby expose ourselves to their rage and enmity, we really save ourselves from them; for, if we consider whither they are hastening, we shall see it is better to have the trouble of swimming against their stream than the danger of being carried down their stream. Those that repent of their sins, and give up themselves to Jesus Christ, must evidence their sincerity by breaking off all intimate society with wicked people. Depart from me, ye evil doers, is the language of one that determines to keep the commandments of his God, Ps 119 115. We must save ourselves from them, which denotes avoiding them with dread and holy fear, as we would save ourselves from an enemy that seeks to destroy us, or from a house infected with the plague.

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.
