When trying to resolve the question of where the source of evil lies in this paradigm it quickly becomes a "pick any two" situation. They can't do this of course, because once you give even an inch you have lost everything.
Oh, your power is not unlimited? Oh, there are forces acting against you of which you have no knowledge, or perhaps you actually don't know what you are doing with all this creation business? Oh, you actually are also the source of all evil?
It much less a compelling argument for many humans to worship a fallible, ignorant, or evil being as the sole power and creator of the universe, as this reminds us too much of ourselves, which is the very state of being one wishes to escape when seeking the divine.
