All reasonable atheists eventually move to the agnostic column when subjected to debate.
There have been a number of “atheists” on FR that were functionally like this. They were willing to live and let live towards believers while still not being sold on God.
And God knows that. And God won’t be caught flat footed. Sometimes the devil really gets some people’s spiritual knickers in a twist, and it takes Jesus hitting them upside the head, so to speak, before they understand where their spiritual bread is buttered. These people are just too busy doing things vigorously in pride to notice God. Jesus had to hit me upside the head. He also did it to Paul in the bible.
