The argument is everywhere. Without the Bible, there would be no morality. Well that’s obviously untrue, since atheists are disproportionately absent in jails.
Blame that on the lack of education of many Evangelicals (especially the home-schooled crowd) if you like, but you’ve got an all-knowing, all-seeing, all-powerful being on your side. We just have science.
But if we’re talking about morality – specifically Biblical morality, there’s quite a gap… it would seem the atheists are more Christian than Christians.
