The religious can rest in the belief that even if they don't know something, their deity knows everything.

So does that mean atheists and agnostics can't rest because they don't know everything? If they can rest, what is it they rest in the belief of?

"Rest," as in to be at ease, in peace. Some people need to know everything, or know that it is at least known by someone, others don't have that need.
