I hope this helps you.<quoted text>Can he make an object so big even he can't move it?
No matter what answer you give, you are defining an entity that is NOT all powerful. Hence the paradox.
"Can God make a rock so big he can't pick it up?
by Matt Slick
This question is representative of the type of paradoxes atheists use in attempts to prove that God cannot exist. It works like this: God is supposed to be omnipotent. If he is omnipotent, then he can create a rock so big that he can't pick it up. If he cannot make a rock like this, then he is not omnipotent. If he can make a rock so big he can't pick it up, then he isn't omnipotent either. Either way demonstrates that God cannot do something. Therefore, God is not omnipotent, and does not exist.
Is this logical? No. The problem is that the argument omits some crucial information and draws an inaccurate conclusion.
What the above "paradox" lacks is vital information concerning God's nature. His omnipotence is not something independent of His nature; it is part of His nature. God has a nature, and his attributes operate within that nature, as does anything and everything else.
For example, I have human nature. I can run. But, I cannot outrun a lion. My nature simply does not permit it. My ability to run is connected to my nature, and I cannot violate it. So too with God. His omnipotence is connected to His nature, since being omnipotent is part of what He is. Omnipotence, then, must be consistent with what He is, and not with what He is not, since His omnipotence is not an entity to itself. Therefore, God can only do those things that are consistent with his nature. He cannot lie because it is against his nature to do so. Not being able to lie does not mean He is not God or that he is not all powerful. Also, He cannot cease to be God. Since He is in all places at all times, if he stopped existing then he wouldn't be in all places at all times. Therefore, He cannot cease to exist without violating his own nature.
The point is that God cannot do something that is a violation of his own existence and nature. Therefore, He cannot make a rock so big he can't pick it up, or make something bigger than himself, etc. But, not being able to do this does not mean He is not God, nor that he is not omnipotent. Omnipotence is not the ability to do anything conceivable, but the ability to do anything consistent with His nature and consistent with his desire, within the realm of his unlimited and universal power, which we do not possess. This does not mean He can violate his own nature. If He did something inconsistent with his nature, then he would be self-contradictory. If God were self-contradictory, he would not be true. Likewise, if He did something that violated his nature, like make a rock so big he can't pick it up, He would also not be true since that would be a self-contradiction. Since truth is not self-contradictory, and neither is God, if he were not true then he would not be God. But God is true and not self-contradictory. Therefore, God cannot do something that violates his own nature."
