The god that revealed himself to Abraham is literally the most complex thing imaginable, as his followers will tell you. He’s been constructed into a being that knows exactly everything you will ever do, yet still finds a way to give you free will so that you can do something that might surprise him. That’s some great power right there. Indeed, as the bible tells us, god can do anything and everything.
Except the things he can’t do. First, as shown in the image above, god cannot lie. (But that’s a contradiction too. I covered it before). Second, he can’t do mighty work, which is a pretty lame handicap for an all-powerful deity. And third, we all know the story of the iron chariots; god couldn’t defeat them. That’s a lot of stuff that god can’t do, despite the fact that he can do anything.
Of course, apologists will probably say that god can do anything; he just chooses not to. That’s pretty convenient of them.
