Acts 2:37-41 - The Response To Peter's Sermon
37 When they heard this, they were pricked in their hearts, and said unto Peter, and unto the other apostles, "Ye men and brethren, what shall we do?"
38 Peter said unto them, "Repent, and be baptised every one of of you in the name of Jesus Christ, for the remission of sins, and ye shall receive the gift of the holy ghost. 39 "For the promise was made unto you, and to your children, and to all that are afar, even as many as the Lord God shall call." 40 And with many other words bare he witness, and exhorted them saying, "Save yourselves from this untoward generation."
41 Then they that gladly received his preaching were baptised; And the same day, there were added unto them about a three thousand souls.
