Acts 2:37-41 NKJV
Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, “Men and brethren, what shall we do?”
Then Peter said to them, “Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit. For the promise is to you and to your children, and to all who are afar off, as many as the Lord our God will call.”
And with many other words he testified and exhorted them, saying, “Be saved from this perverse generation.” Then those who gladly received his word were baptized; and that day about three thousand souls were added to them.
