It illustrates Jesus’ death and resurrection (1 Cor. 15:3-4, Col. 2:12), as well as your new life as a Christian (2 Cor. 5:17, Rom. 6:4). Baptism doesn’t make you a believer; it shows that you already believe. Baptism does not “save” you, only your faith in Jesus does that. Baptism is just like a wedding ring– it’s the outward symbol of the commitment you made in your heart (Eph. 2:8-9).
