"God help him" is simply a cultural expression, Riginslinger. It means, "I hope he makes it through somehow, despite the very long odds."...but it's quicker and easier to say.

Here are a few more:

"God knows" - means "I haven't got a frikkin' clue about that"

"God willing" - means "If my luck holds. Got my fingers crossed on this one..."

"Good lord!" - means "Holy shit!" or "Say whattttt??????"

"Heaven knows" - See definition of "God knows" above.

"Jesus H. Christ!" - see definition of "Good lord!" above...

Now if you find any of them objectionable on atheist grounds I seriously suggest you seek emotional counseling... ;-)
