What happened in the old testament that reveals the meaning behind baptism. 1 Peter 3:20-21 Why doesn't the amount of water matter in baptism?
What does water doesn't save us, nor does the amount of water but rather the water is an outward expression to others of an inner change by the Holy Spirit.1 Peter 3:20-21
1 Peter 3:20-22Amplified Bible (AMP)
20 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. 21 Corresponding to that [rescue through the flood], baptism [which is an expression of a believer’s new life in Christ] now [a]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,
So Baptism indicates that the Old Adam in us should by daily recognition of sins and repentance be drowned and die with all sins and evil desires, and that a new man should emerge each day and to live before God in righteousness and purity forever. It is not the physical water that saves but faith in Christ Jesus.
