Omniscience is fundamentally incompatible with free will. Someone with true free will can exercise their judgement in making choices in their life. If God is truly omniscient, then he already knows the results of those choices before they are made. Logically, this implies that there was only one possible choice to begin with - the choice God knows about. All other choices were illusory because you were for-ordained to choose the option God knew you would choose. If he does NOT know and learns as you make those choices, then he is no longer omniscient.

Omnipotence is inherently contradictory because it pits creative ability against performance. If you can create anything, then you can create a puzzle no one can solve, an unliftable object, an intangible force ... and yet having no limits to your performance, you can solve that puzzle, lift that object and perceive or sense that force. The two sides of omnipotence cancel each other out in a logical conundrum.

Nope. They logically contradict one another. If god is all-knowing, or knows the future and the past (i.e. is has a "plan for everybody"), then if he cannot change the future or the past, as it is set. Thus he can't be omnipotent. If he does change the flow of history, then he didn't know the future or the past, meaning he was not omniscient.

Furthermore, omnipotence even contradicts itself. Can god make a rock so heavy he can't lift it himself? This may sounds childish, but it holds a great truth.

If God was omnipotent and elected to without power entirely, or without any one certain power then God would no longer be omnipotent... Same argument for omniscient. Your point it moot.

I recently read a poem that I think sums up the paradox pretty well.

Can ominscient God who,

Knows the future find,

The ominpotence to

Change his future mind?

Basically if God knows everything that is and will be, this includes how he/she will use his/her omnipotence in the future. However this means one of either two things;

1. God isn't omnipotent, because he/she doesnt have the power to change his/her mind about the future that he/she already knows, or

2. God isn't omniscient, because if he/she does change his/her mind about the future it means he/she didn't know everything that would happen in the future

The obvious rebuttal to this paradox is that God does have the power to change his/her mind but has never execised it. However can a power that you can't use be classified as a power at all?

God cannot be omniscient and omnipotent because there is no god.
