You guys are all too blind imho, to see the truth behind all your religious texts.
It is not even important if Jesus lived as a real person (or god or whatever).
Don't missunderstand me: I try to live after his example. But the important thing is just to try to live like he told us. If someone just invented him as part of a story to tell us about "christian" idea(l)s, or if someone really lived like that make not difference in any way.
An example:
A fried of you tells you that he has a guy friend who said you are the greatest guy ever! You don't know that guy and there is no way of you ever meeting him.
Now is there a difference if the guys does exist or not? Remember: you will never know if he is even real. You just have to trust your friend about it.
It feels good anyway, right?
And that's all behind bible, thora etc. You rely on a guy telling you something. That's ok. We all do this all the time.
The important part here is just, that we remember that it is that way. And not that you friend told you the absolute truth!
