In your opinion what causes christians to believe in Jesus

[Sheldon]

To me, it's intellectually lazy not to be able to even contemplate the possibility of things. 

You seem to be falsely implying that disbelieving the claim a deity or deities exists, or are possible, is somehow a closed minded claim, that deities can't exist, and are impossible, I am not sure why this error has to be explained over and over? There is no intellectual laziness in demanding claims be properly evidenced, quite the opposite in fact. 

Present or demonstrate a single reason that a deity or deities are possible, and we can proceed to examine it. It is your refusal / inability to do this, while doggedly clinging to the claim, in an atheist forum, that amounts to intellectual laziness, nay intellectual dishonesty. 

The irony of course, is that most atheists are open, honest, and unequivocal about what they do and do not believe, whereas you refuse to be questioned, offer generic and often facile claims, and define words arbitrarily, often at odds with common usage, while demanding others define a phrase like objective evidence, as if combing the two words, is as indecipherable as the phrase "spiritual conviction", which defines religious faith. 

I guess when one is dealing in unevidenced and inexplicable magic, it seems reasonable to be vague and mysterious, but to then stridently demand explanations of a two word phrase, when a cursory look in any dictionary would do, just seems dishonest to me.
