It doesn't really matter if there was a virgin birth or if someone could walk on water for me to believe that divinity (or human capacity for it) somehow exists.
To put it in Dostoevsky's words:
"s'il n'existait pas Dieu il faudrait l'inventer. And true enough, man has invented God. What is so strange and extraordinary is not that God really exists but that such a thought -- the very idea of the necessity of God -- should have occurred to a vicious wild animal like man, for that concept is so holy, so touching, and so wise that is does man too much honor."
I'd been so proud about being smarter and more inquisitive for some truth that I became unkind. Wanting to be smart, and being curious are certainly good things and a part of my concept of (and the pursuit/bidding of) God, but love and humility are essential.
So to be more like Jesus...
