Acts 2:37-41 - The Response To Peter's Sermon
37 And hearing this, they were pierced to the heart, and said to Peter and the rest of the apostles, Brethren, what shall we do?
38 And Peter said, Repent, and be baptized every one of you, in the name of Jesus, for the remission of sins, and ye shall receive the gift of the Holy Ghost. 39 For the promise is to you, and to your children, and to all that are afar off, whomsoever the Lord our God shall call. 40 And with many other words did he testify and exhort, saying, Save yourselves from this perverse generation.
41 Then they, gladly receiving his word, were baptized; and there were added to them that day about three thousand souls.
