Acts 2:37-42

Now when they heard this, they were pierced to the heart, and said to Peter and the rest of the apostles, “Men, brothers, what should we do?” And Peter said to them, “Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit. For the promise is for you and your children and for all who are far off, as many as the Lord our God will call to Himself.” And with many other words he solemnly bore witness and kept on exhorting them, saying, “Be saved from this crooked generation!” So then, those who had received his word were baptized; and that day there were added about three thousand souls. And they were continually devoting themselves to the apostles’ teaching and to the fellowship, to the breaking of bread and to the prayers.
