2:41 {10} Then they that gladly received his word were baptized: and the same day there were added [unto them] about three thousand souls.
(10) A notable example of the power of the Holy Spirit: but such are not baptized until they make confession of their faith. (Ed.)
2:41 They that gladly received his word. Every believing penitent would gladly receive it.
Were baptized. Not indefinitely in the future, but that day.
The same day there were added about three thousand souls. Hackett, in his Commentary on Acts, writes:
It is proper to add that pools numerous and large which encircled Jerusalem, as both those still in use, and as the remains of others testify of at the present day, afforded ample means for the celebration of the rite of baptism. The habits of the East, as every traveler knows, would present no obstacle to such a use of the public reservoirs.''
It has been objected to the immersion of the three thousand that the apostles could not have done it in one day. We are not told that the apostles only were the baptists, or even baptized at all. There were at least 120 disciples there; perhaps even more on this great day. Perhaps the Seventy were all there. But the apostles alone could have discharged the office. There would be 250 to each one. Sixty persons have been immersed easily in an hour by one person. At this rate the whole work could have been accomplished by twelve men in about four hours. The celebrated Chrysostom, aided by his elders, baptized (immersed) 3,000 in a day in A.D. 404.
2:41 And there were added - To the hundred and twenty.
2:37-41 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.
