Radosh, in his book Rapture Ready: Adventures in the Parallel Universe of Christian Pop Culture, says:
... do Christians simply find a personal comfort zone and construct a theological and cultural justification around it?I say yes. However, not just Christians, but all of us. This is the natural, primal task of the brain for the human organism. The brain's fundamental occupation is to make itself secure and to justify that security with apparently logical explanations. Everyone from the religious fundamentalist to the atheist does this. We find our own place of comfort and justify it with ideologies. We want to understand our world. It must have meaning. The deep and perpetual need of the brain for the physical security of the organism is intrinsic. Until we humbly understand this we will never get anywhere.
