The Second Problem Is That God Doesn't Exist

In order to exist, a thing must have the potential to remain in existence as it is. Alex's next argument seems to be that God has no potential whatsoever. But unless God is about to stop existing, he must have at least one kind of potential,. which is the potential to stay as they are. And this brings us to Alex's objection to the argument from motion. Just because some things have a potential to remains in existence, it doesn't follow that all things have this potential. Therefore God does not exist.
