Acts 2:37-41 - The Response To Peter's Sermon
37 Now when they heard this, they were pricked in their heart, and said to Peter and to the rest of the apostles, Men, brethren, what shall we do?
38 Then Peter said to them, Repent, and be baptized every one of you in the name of Jesus Christ, for the remission of sins, and ye shall receive the gift of the Holy Spirit. 39 For the promise is to you, and to your children, and to all that are afar off, even as many as 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 that gladly received his word, were baptized: and the same day there were added to them about three thousand souls.
