In your opinion what causes christians to believe in Jesus

[Sheldon]

My argument is that only one sense exists within Christianity—that of trust. The other senses are as irrelevant as it is to point out that bank also means the edge of a river when I'm trying to deposit money. These might as well be different words, so there's no reason to acknowledge them as having equal merit.

So your faith in Jesus is not based on spiritual conviction?

He said (his faith) equates to trust, and that trust requires good reasons, he refuses to offer any though. insisting we must first accept without any evidence that a deity is possible. This kind of stridency is how religious indoctrination works of course, it is not be questioned, but it only works when being offered to children who don't know they can question it, or how, or when what is being offered is not a choice. I am reminded now of the late Christopher Hitchens quote: 

“Many religions now come before us with ingratiating smirks and outspread hands, like an unctuous merchant in a bazaar. They offer consolation and solidarity and uplift, competing as they do in a marketplace. But we have a right to remember how barbarically they behaved when they were strong and were making an offer that people could not refuse.”
