We're not saved by baptism. That's Christianity 101. How could you even be wrong about that?

(Ephesians 2:8-9 NIV) For it is by grace you have been saved, through faith--and this not from yourselves, it is the gift of God-- {9} not by works, so that no one can boast.

We're saved by repenting of our sins and accepting what Jesus did on the cross as the only necessary payment for our sins. And we must accept Jesus as Lord.
