The above paragraph is total nonsense  It has no meaning  Saying God is a paradox is equivalent to saying God cannot exist and I dont think that was your intent  In addition claiming that infinity cannot be understood is a vague statement at best and even if true it still wouldnt be an argument for the existence or omnipotence of a god  Lastly you clearly didnt understand the Godrock argument so let me try to help  If you claim the answer is yes then God has a limit if the answer is no then God also has a limit  Therefore God or any being for that matter must have limits of some kind  Saying he could choose to not be able to implies that he could choose to be capable of it and therefore one can simply conclude that he is capable of that act
