Sure, I've done plenty of research to justify a belief in God, however I have found that the Bible if read literally presents multitudes of logical fallacies, false statements, and impossible accounts. In order to rationalize these things one must repurpose and misinterpret the Bible to fit reality beyond my personally acceptable peramiters. I also find that on a denomination to denomination, church to church, fellowship to fellowship, and person to person basis, there are far to may variations and doctrines that conflict with each other and all claim to be the truth. There is no possible way for me personally to fully accept the Christian religion, or any others including those which demonstrably predate the judo Christian religion as a logical explanation for my existence, without faith.
