Acts 2:41

the sermons of the apostles, or of our Saviour, are not all set down by the holy writers; but only so much as God saw necessary for his church to know and believe. using God’s name and authority, and calling him as it were to witness. no less than the salvation of our souls depends upon our forsaking wicked and profane persons in their ungodly courses. From this untoward generation; the whole world lies in wickedness; but especially the scribes and Pharisees, and other such declared enemies of Christ Jesus.

IV. Here is the happy success and issue of this, v. 41. The Spirit wrought with the word, and wrought wonders by it. These same persons that had many of them been eye-witnesses of the death of Christ, and the prodigies that attended it, and were not wrought upon by them, were yet wrought upon by the preaching of the word, for it is this that is the power of God unto salvation. 1. They received the word; and then only the word does us good, when we do receive it, embrace it, and bid it welcome. They admitted the conviction of it, and accepted the offers of it. 2. They gladly received it. Herod heard the word gladly, but these gladly received it, were not only glad that they had it to receive, but glad that by the grace of God they were enabled to receive it, though it would be a humbling changing word to them, and would expose them to the enmity of their countrymen. 3. They were baptized; believing with the heart, they made confession with the mouth, and enrolled themselves among the disciples of Christ by that sacred rite and ceremony which he had instituted. And though Peter had said, "Be baptized in the name of the Lord Jesus" (because the doctrine of Christ was the present truth), yet we have reason to think that, in baptizing them, the whole form Christ prescribed was used, in the name of the Father, the Son, and the Holy Ghost. Note, Those that receive the Christian covenant ought to receive the Christian baptism. 4. Hereby there were added to the disciples to the number of about three thousand souls that same day. All those that had received the Holy Ghost had their tongues at work to preach, and their hands at work to baptize; for it was time to be busy, when such a harvest was to be gathered in. The conversion of these three thousand with these words was a greater work than the feeding of four or five thousand with a few loaves. Now Israel began to multiply after the death of our Joseph. They are said to be three thousand souls (which word is generally used for persons when women and children are included with men, as Gen 14 21, margin, Give me the souls; Gen 46 27, seventy souls), which intimates that those that were here baptized were not so many men, but so many heads of families as, with their children and servants baptized, might make up three thousand souls. These were added to them. Note, Those who are joined to Christ are added to the disciples of Christ, and join with them. When we take God for our God, we must take his people to be our people.

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.
