Water baptism is by immersion after genuine repentance and acceptance of Jesus Christ as personal Savior. It symbolizes the death and burial of a sinner into the death and burial of Jesus Christ. Rising out of the watery grave symbolizes His resurrection. Also symbolizing purification, baptism prepares one for the receipt of the Holy Spirit. When one rises from his watery grave, he is to be a new person, led by God's Spirit and conducting his life according to God's way.
