Sometimes questions about God come in from folks that are full of good sound reasoning. There are other questions that are demonstrative of what I would call confused categories. Here is one you may hear that would fit this classification. The question is: Can God create a rock so big that He is not able to lift it?
Of course when you talk about God, we are talking about a being that is all powerful (omnipotent). At the same time, just because God is omnipotent, it does not mean that He can do literally everything. "What? What are you talking about? God can do everything!" The response to this emotional tirade is, "Can God do anything that will violate His will or His nature?"
The answer to that question is, no. God cannot lie. Why? Because God is truth and He will never violate His nature and the holy demands of His character.
God cannot make a square circle, because a square by definition is a four sided figure and a circle has no sides (some would say it has one side); therefore notion of a square circle is self–contradictory. And God cannot and will not cease being God, the only entity in existence, the reason for whose existence is in Himself.The question at hand about God creating a rock so big that He cannot lift it is one of confused categories. The rock was created, by....God, an infinite (all present, all knowing, all powerful and all loving) Being in every facet of His essence. If an all powerful Being can create anything, that Being will be able to move it as well.
