I marvel at the mystery of how one can proclaim that faith is irrational. Show me a theoretical model of how the universe [or us for that matter] came into existence, and I will show you something that will ultimately be accepted by faith--by the "believer".
A better question is what faith is more rational or reasonable?
It is in this instance or realm, where Christ-based philosophy stands heads and shoulders above the rest. Take the Resurrection for example; it does not suffer for lack of historical evidence--it is generally disbelieved simply because it is "unbelievable".
Well, is it believable that the Milky Way has 200 billion stars in it, is it believable that the keys on your PC key board "aren't really there", in quantum physical terms?
Is is believable that we are even here??
How is unbelief justified in the case of the Resurrection of Christ, in the face of the rest of the unbelievables? To disprove the Resurrection requires more than sheer unbelief.
