This is a symbol of baptism, which now saves you-- not the putting away of the filth of the flesh, but the answer of a good conscience toward God, through the resurrection of Jesus Christ,
"Baptism doth also now save us!" (1 Peter 3:21). "Repent and be baptized...for the remission of sins" (Acts 2:38). "Arise and be baptized, and wash away thy sins" (Acts 22:16). "He that believeth and is baptized shall be saved" (Mark 16:16).
