Everything comes from something. Every effect has a cause. This is a law of logic and a fact of science. Christians believe that God created the universe and everything in it. God is the cause of everything that exists. But, doesn't God also need a cause? What caused God to come into existence? Who created God? These questions are often used by critics in an attempt to discredit the idea that God created the universe. If God is the cause of the universe, then what is the cause that resulted in God?
Who created God?
The problem with this argument is that it is built on a faulty assumption. It is not true that everything has a cause. From nothing, nothing comes. If there was ever a time when nothing existed, nothing would have ever come into existence. There had to be an uncaused cause that caused everything else to come into existence. You can't go from absolutely nothing to something, so there must have always been a something. That something, or more accurately, someone, is God.
God is the uncaused cause that caused everything else to come into existence. God is the uncreated Creator who created the universe and everything in it (Genesis 1:1). The question "Who created God?" is invalid at its core because it rests on the faulty assumption that God is subject to the laws of the universe that He created. Yes, now, everything has a cause. Yes, now, something cannot come from nothing. But, without the first uncaused cause, nothing else would exist. God is the One who set everything into motion, including the logical and scientific fact that every effect has a cause.
The "Who created God?" question is deceiving because it is based on the false assumption that God came from somewhere. If God was created, then He is not the sovereign, eternal, infinite, and all-powerful God who is described in the Bible. That is the true reality behind the question. It is an attack on the Christian faith's understanding of God. But, the question/attack is invalid at its very core. God as the Creator is not bound by the laws of what He has created. God is uncaused and uncreated—He simply exists, and always has, and always will.
