The Christian God said he would make everyone who was not a Christian burn in hell, and he didn't do that as far as I know.
Odin said he would kill the Frost Giants, and I don't see any Frost Giants.
Odin:1
God:0

It's not God saying "you're going to burn in hell because you don't believe in me." It's the rejection of Jesus, the bridge between God and man, that cleanses sin. When you die your spirit is perfected, and a spirit body of that caliber feels the full force and devastation of sin, hence hell.
