@dubstepped,
If a person wrote about himself performing miracles and just being great and on a first name basis with God..... yeah that would be suspicious (Moses anyone?).
But what if Jesus at least wrote down the parables he (allegedly) told? All the important stuff we really need to know?
And then 3 gospels written by eye witnesses would be a testimony to Jesus' authority and wisdom, increase his credibility, etc.
That would really work...
But now we have accounts written ages later, with some stories almost identical, but with enough contradiction for us to be forced to say 'these are accounts of separate events'...
