Well, reguardless of wether or not you beleive in God or Christianity, the Bible is filled with historical and bibliografel facts. Even more, it is chop full of useful lessons and advice for us to use. Just read Romans.
The LAST thing I would ever due is rip out someones beleifs and cram my own inside. You won't get anywhere with that except for trouble. None the less, there are alot of things you can check out.
This is hypacritical coming from me, but even though Naruto is fictional it has some really good examples. Rock Lee was knocked down and treated like crap. The only thing he was able to do was something he was bad at--worse than anyone else. Did that stop him? NO!!! His will and determination drove him further and fuled his ambitions to the point where he's one of the (if not THE) greatest taijutsu masters in Konoha. This shows us that hard times, trials, and the crap of life can make us even stronger if we hold on to something and make the RIGHT choices.
The Bible is chop full of things like this.
