The answer lies in the answer to my question.
Still, I believe in mathematics because it works. Why do you believe in the god of the Christians to the exclusion of all others?
Similarly, Jesus is a real person, not an emotional crutch. An absolute truth, not a relative choice. Like 2+2=4 and not 2+2=5.
How do I prove it? Simple. Ask Jesus himself to show that he is real, to you. However when you ask, you cannot have an attitude - otherwise he will ignore you.
"you will seek me and find me when you seek me with all of your heart" [God] (http://www.biblegateway.com/passage/?search=Jeremiah%2029%20:%2013;&version=31)
He himself, will checkmate you.
It will not always be in the same way.

So why do you believe in the god of the Christians to the exclusion of all the other gods?
