Then Peter continued preaching for a long time, strongly urging all his listeners, “Save yourselves from this crooked generation!” Those who believed what Peter said were baptized and added to the church that day—about 3,000 in all. All the believers devoted themselves to the apostles’ teaching, and to fellowship, and to sharing in meals (including the Lord’s Supper), and to prayer.
