I am genuinely curious what these conflicting attributes are in your view.
But also, from a dialectical lens, contradiction exists in all things in our own observable reality, from the lowest levels of the concept of movement to the highest levels of the organization of human society. Why would a seeming contradiction be proof that God cannot exist?
Arguments for God’s existence (such as classical theistic arguments) are not merely isolated truth claims—they function at the paradigmatic level, offering a foundation for knowledge itself.
If you deny God’s existence, you must account for the reliability of reason, logic, and abstract universals like mathematics. If these are simply “self-evident,” then you’re assuming the very thing your worldview has no means to justify.
Assuming you don't believe in God...
without a transcendent source of rationality, why assume logic is binding or that it applies universally?
Basically you're in no position to determine whether God is imperfect or not if you can't justify the tools you use to make that assessment.
I don't believe it would. Perfection can, and insofar as perfection exists in our reality does, exist alongside perceived contradiction as contradiction exists in all things.
The god that the isrealites originally worshipped was a rather weak storm god.
Somehow over the centuries, its cult has conflated it into some all powerful entity.
If it were to stay in its original manifestation, I still wouldn't believe it existed, but I would take a more agnostic approach to it - as I do with gods from other myths.
