Acts 2:37-41 - The Response To Peter's Sermon
37 Now having heard this, they were pierced in the heart, and said to Peter and the other apostles, Men, brothers, what will we do?
38 And Peter said to them, Repent ye, and be immersed each of you in the name of Jesus Christ for the remission of sins, and ye will receive the gift of the Holy Spirit. 39 For the promise is to you, and to your children, and to all those in afar, as many as Lord our God may call. 40 And with many more other words he testified and exhorted them, saying, Be saved from this crooked generation.
41 Indeed therefore those who received his word gladly, were immersed. And there were added in that day about three thousand souls.
