A...Repent believing that Jesus Christ is the Son of God, or God the Son. Read( Mat. 1:23, Isaiah 9:6) All have sinned. Repentance is godly sorrow for our past sins Read (Rom. 13:14).
B...Be emerged baptized in water, in his name (Jesus) buried with him for remission of our past sins: raised out of the water to walk in newness of life (the likeness of His death, the likeness His resurrection.) Read Rom. 6:5, Acts 1: 8..
C....Receive the spirit of our God the Holy Ghost. We first believe to receive, have you received since you believed?( Mary the mother of Jesus didn't receive until she had first believed what the angel said.) so it is with us. So Ask Yourself This Question: Have you received since you believed? Read ( Acts 19:2)
