Nobody’s impressed by water, but baptism saves.

The power, work, profit, fruit, and end of Baptism is this, namely, to save. For no one is baptized in order that he may become a prince, but, as the words declare, that he be saved. But to be saved, we know, is nothing else than to be delivered from sin, death, and the devil, and to enter into the kingdom of Christ, and to live with Him forever.
