What are the Characteristics of a NT Christian?

[SteveII]

{A} I believe the events in the Gospel happened pretty much as described.  I have never heard a coherent theory that would explain the widespread belief that we have evidence for following the death and resurrection of Jesus. 
{B} If I believe in God, why isn't the NT compelling? It makes sense, it answers many questions, it provides details on living a fulfilling life, and provides a way to have a relationship with God. Also do not underestimate the role of personal experience (changed lives, attitudes, etc.) of the person and of other Christians that adds to the evidence.
{C} What is the difference between all the other religions and Christianity? The NT. I think it delivers the most complete systematic theology of any religion by far.

Thank you for your response, SteveII.  If you're interested, I'm still unsure about how one can prove the truth of your religion via a purely rational approach.  Can the truth of your religion be proven outside of the NT?  For example, when proving a math theorem, it would be incorrect to prove its truth via the claim/conclusion of the theorem itself: in order to prove it, outside definitions (exact and precise) and the results of other theorems, lemmas, corollaries, etc., must be logically connected in order to clearly establish the truth of each premise , so that the conclusion is reached via a logical flow of evidence and facts.  Hence, like a math proof, could the truth of your religion be proven in a similar fashion?

Analyzing historical events is nothing like a math proof. You look at all the evidence and decide if the you think the events happened as portrayed. I have never heard a feasible alternate explanation as to why we have (in chronological order): 1) the existence of many churches throughout the empire prior to 50AD, 2) the letters of Paul writing to these churches (and his journeys to visit them)--who already believed the core of Christianity, and 3) the gospels and Acts. 

So, since I have no problem believing in the supernatural, have evidence that the events of the NT happened, and have no compelling counter-evidence or feasible scenario to explain the evidence we do have, I am rationally justified in believing that Christianity and its claims are true.
