You’re very close to being correct here.
If there is a god (created by God) who is more powerful than God, then there isn’t the need for the created god to “put will into action.” In terms of the created god’s nature, he is already not subject to the power of God.
But, if we correct your analysis, we run into a problem… you devolve into paradox: if God cannot, he isn’t all powerful. If God can, He isn’t all powerful. Yet, how can a non-omnipotent God create omnipotence? Paradox.
The problem is, you have other issues: how can a god who must be
created be all-powerful? That is, he is not the cause of his existence, and therefore, because there is a god who
is the cause of his existence, there’s a god who has a power that he doesn’t. Paradox.
But wait… there’s more. What makes God ‘god’ is his unchanging perfection. If there’s the possibility that there could be a more perfect being than God, then He’s not god to begin with. So, if He
could do so, then that implies that he was never god to begin with, and therefore… paradox.
So, since your thought experiment leads to paradox on all counts, we have to ask why you’ve painted yourself into this corner to begin with. The solution is simple: you’re asking for a logical impossibility. So, this has nothing to do with God and His power; rather, you’ve asked a question that is logically impossible from the very begin. This is a logically untenable question.
