Atheists who become Christians

[abaris]

Isn't it hugely arrogant to presume that there can be no good reason to convert to Christianity.

Religion is in itself not rational. You have to accept certain things at face value, certain supernatural things to be precise.

One can be otherwise rational and still be religious. But religion is faith and fatih is emotional. Nothing wrong with that, since we're all emotional about one thing or the other. But it has nothing to do with reason.
