Can God create a rock so big he cannot lift it?
But if you believe God can't create a rock so big he can't lift it, then you are reducing God's omnipotence.
But the question doesn't make sense, because it assumes something that is logically impossible.
But 'with God, all things are possible.' The Bible says as much. So you're diminishing God's omnipotence.
Yes, but statements like that in the Bible need to be interpreted properly; not everything means what it says at face value. (Otherwise Jesus was telling us to go cut off our hands whenever we sinned.) God's omnipotence must be defined Scripturally, not broadly.
If we just use the word 'omnipotent', we come away thinking God can do absolutely anything
, including logical impossibilities.
Our concept of 'omnipotent' must instead be filtered by what Scripture teaches, and also by the tool of logic (which is a gift from God, and not something inherently anti-God). Scripture teaches that God is 'Almighty', but it never depicts him doing something logically impossible. And basic logic tells us that logically impossible things are, well, impossible. God cannot create a rock so big he cannot lift it because by Scriptural definition, God is immeasurably superior to the things he creates. By logic, God cannot draw a square circle, because a 'square' and a 'circle' each have their own definitions that contradicts the other.
Scripture also tells us that God 'cannot lie'. Well, what does this mean, that God is so weak-willed that even if he desired to lie, he couldn't do it? Of course not. For God to 'lie' would be a logical contradiction, because God is
truth. A true thing cannot be a false thing, and vice versa. Since God in his nature
is true, he cannot be false. Since God by his nature is truth, he cannot lie.
To believe that there are certain things God cannot do
does not mean our belief is 'reducing' or 'diminishing' who God is. It is simply recognizing
a basic fact about who God is. For God to be 'omnipotent' does not mean God can do absolutely anything
; it means he is capable of doing things which are logically possible, and which do not contradict his own being.
