Acts 2:37-41 - The Response To Peter's Sermon
37 Now when they heard this, they were stabbed to the heart, and said to Peter and to the rest of the apostles: Men and brothers, what shall we do?
38 Then Peter said: Repent, and be baptized every one of you in the name of Jesus Christ for forgiveness of your sins, and you will receive the gift of the Holy Spirit. 39 The promise is to you, and to your children, and to all that are afar off, even as many as Jehovah our God calls. (Micah 4:5) (Deuteronomy 6:4) 40 He gave a thorough witness with many words and exhorted them, saying: Save yourselves from this indecent generation.
41 Those who gladly received his word were baptized. About three thousand persons were added the same day.
