Then we can argue that omnipotence as a concept, does not exist. A better attribute would be "very powerful", but claiming anything or anyone to be "all powerful" is illogical.
In the bible, god is not omnipotent, he is rather "very powerful". He is limited by constraints such as his inability to sin. The bible's view on omnipotence is incorrect.
Then there's the matter that an "omnipotent" deity should be able to do theoretically anything, even outside the boundaries of logic and math. But by definition, an omnipotent deity cannot be omnipotent, showing the invalidity of the concept, "omnipotence" (The "stone so heavy he can't lift it" paradox in omnipotence is valid).
Omnipotence implies that an omnipotent entity can place constraints upon itself such that it is both omnipotent and non-omnipotent simultaneously. If omnipotence is the defining characteristic, then adding constraints via that omnipotence in no way changes its identity.
Omnipotence paradoxes are necessarily self-resolving.
This is what the God of the Bible did. He is great beyond the greatest ideas of greatness that we can begin to have.
God did it in the person of Jesus, Who was God as well as man. God died in Jesus, and yet He lives forever in the form of the Father and the Holy Spirit. Perhaps the whole making of the universe and mankind was God's method of showing the devil and all the angels that God can be omnipotent and not.
Sometimes I wonder if the God of the Bible is as Triune as Christians say. There is evidence that God is far beyond Triune in that people are part of God. People are even above the angels. Jesus quotes the Old Testament saying that we are gods. We might simply be the method God used to be omnipotent at the same time He was not.
The biblical view of omnipotence is not true omnipotence, rather god in the bible is simply "very powerful". In the bible god cannot sin, and christ does not know the day he is to return on his 2nd coming, so that means god in the bible lacks both omnipotence and omniscience.
Yet people sin. And they are being drawn into Godness, into the Body of Christ, and He in them. So, in a way God sinned even while He did not.
The fact that Jesus didn't know certain things was simply that he set that knowledge aside temporarily, the same as He set His full spiritual form aside when He came as a baby at Bethlehem.
