Sure I did, but just to be more clear....I'm stating that there are things that God can't do. And it's based on Scripture. God Himself tells us here.....
Hebrews 6:17-19 Because God wanted to make the unchanging nature of his purpose very clear to the heirs of what was promised, he confirmed it with an oath. God did this so that, by two unchangeable things in which it is impossible for God to lie, we who have fled to take hold of the hope offered to us may be greatly encouraged.
Buck, metmom is correct. God is incapaple of lying. He is incapable of sin. Why? Because both those things violate his very nature. Spiritually speaking, it's like asking a human to breathe water and remain alive. We can't do that because it violates our nature.
Similarly, there are things that God can't do that violate logic. For example, God cannot create both an immovable object and an irrestible force.
