If he truly did not believe in God, the baptism would not matter to him.

I agree. His baptism was probably nullified along time ago(if you are arminian) or was never valid to begin with(if you’re calvanist) :-)

exactly. Doesn't his complaint sort of validate what he's trying to nullify? It's like, "God, I know you dont exist!"

Yeah, he’s probably mad at God because it isn’t a Utopian world. Don’t we all wish we could undo some things but reality is reality and if it happened who but God can take it back? He can renounce it, wish it didn’t happen, call his parents and the church all kinds of names but what’s done is done.

Precisely. He is mad at God.

I once let a girl do my astrology horoscope, but I don't spend my days trying to go back in time 30 years and have it undone.

Well put.
It really demonstrates how angry and hurt he was and is. There's no remedy for him in this world. He's made his choice. Only God can help and mend him.
