I wonder what He would think of an M1 Abrams

I am reminded of this tastey verse from the bible by the good people over at The Atheist Experience (whose broadcast I enjoy religiously):

"And the LORD was with Judah; and he drave out the inhabitants of the mountain; but could not drive out the inhabitants of the valley, because they had chariots of iron - Judges 1:19 "

They even put up a counter apologetics wiki based on the idea. It is a solid resource for some of the more popular apologetic arguments you might come across.
