There's two things there, and I don't get either of them.
First, if you want to sidestep if Jesus is omnipotent, then it's no longer saying anything about omnipotence.
Second, you also have to make the devil omnipotent.
Actually, the second point has a sub-point, because if it's two different entities then you get "an unstoppable force meets an immovable object" which is more easily resolved by "the force just passes right through the object without influencing it" — for the self-contradiction I gave to even be present, you would need to regard the devil as being another aspect of Yahweh in the same regard that Jesus is an incarnation of Yahweh within Christianity (not to be confused with how Jesus is seen in Islam, which totally rejects this as polytheistic idolatry).
