In 1 Peter 3:21, Peter clearly taught that baptism was not a ceremonial act of physical purification, but the pledge of a good conscience toward God. Baptism is the symbol of what has already occurred in the heart and life of one who has trusted Christ as Savior (Romans 6:3-5; Galatians 3:27; Colossians 2:12).
Katika 1 Petro 3:21, Petro alifundisha wazi kwamba ubatizo haukuwa tendo la sherehe ya utakaso wa kimwili, bali ni ahadi kwa dhamiri njema mbele ya Mungu. Ubatizo ni ishara ya kile tayari kimetokea katika moyo na maisha ya mtu ambaye amemwamini Kristo kama mwokozi (Warumi 6:3-5, Wagalatia 3:27, Wakolosai 2:12).
