The Value of Baptism

The water and baptism has no value in it of itself. It's not magical water. You can't pour it on someone who's possessed with a demon and they'll burn. The rainbow has no power to stop a flood. What's going to keep a flood from ever coming on this earth again? God keeping his promise, right? Baptism is not grace. It'snot justification, sanctification, glorification, right? It's a means of grace. And it functions just like a credit card.
