In your opinion what causes christians to believe in Jesus

[Sheldon]

It sounds like a person trying to negotiate with an empty hand. 

I've assessed my audience correctly. 

Nope, though you've more likely made biased and subjective assumptions, that reflect the very poor reasoning your arguments have thus far demonstrated. 

Look how difficult it is just to have Sheldon grant conceivability. 

A bare faced lie, I just understand, as you clearly do not, that conceiving something, in no way demonstrates it is possible. The every assertion is beyond asinine. 

We're scraping the bottom of the barrel here, short of asking if he can at least imagine it.

Can you imagine a flat earth? Does this really infer a flat earth is possible to you? This is comedy gold. Almost as funny as when you claimed you had bested the entire scientific world, and falsified species evolution.
