I bet every atheist has heard Christians claiming that they used to be an atheist. When I hear that, I always ask them why they were an atheist and invariably discover that they were not really atheists at all—they were lazy Christians. Instead of praying/going to church they preferred drinking/sex/drugs/gambling or other self-indulgent pursuits.
Then I ask why they changed their minds and they always give me an emotional reason—they had an experience of some kind and discovered Jesus. What I never hear is “I found the ontological/cosmological/teleological argument…” [or whatever].
Well, in my opinion, if you were an atheist for no logical reason, you were a bad atheist and if you are now a Christian for no logical reason, you are a bad Christian.
If logic takes you to atheism, you will almost certainly remain an atheist because no matter how much your life changes, logic will stubbornly stay the same. The beauty of logic is that it does not depend upon how you happen to feel today.
