1 Peter 3:20-21

who once were disobedient, when the great patience of God was waiting in the days of Noah, during the building of the ark, in which a few, that is, eight persons [Noah’s family], were brought safely through the water. [Gen 6-8] Corresponding to that [rescue through the flood], baptism [which is an expression of a believer’s new life in Christ] now saves you, not by removing dirt from the body, but by an appeal to God for a good (clear) conscience, [demonstrating what you believe to be yours] through the resurrection of Jesus Christ
