Sometimes in defending the existence of God the question arises, “who made God?” The short answer is no one did. That question assumes he was created in the manner Zues or Thor were created. Not true. He is the uncaused first cause. He is necessary because all things as we know them arise from the law of cause and effect. Without getting too deep here, it’s important to know that it’s impossible to have an infinite regression of causes. In the words of President Harry Truman, at some point someone must say, “the buck stops here.”
Some people have difficulty understanding how God can just “be” there without a beginning. First of all, the only way for anything to “begin” is for it to operate within time itself. The words “begin” and “end” are dependent on time. But since God is not bound by time he must then transcend it altogether.
We know from Big Bang cosmology that time, space, energy, motion, etc., had a beginning at the instant the Big Bang occurred. Since time had a beginning it had to be created. Moreover, it had to be created by something that is separate from it. Time can’t create time. Nature cannot create nature. Those notions are examples of illogical circular reasoning.
To illustrate how time and God are separate think of a farmer building a pond for the benefit of his cattle. The farmer creates the pond but he is separate from it. He transcends it. In our world of time, sometimes God enters time through miracles, providential acts, incarnation of himself through Jesus, etc. The same can be illustrated with the farmer and his pond. The farmer created the pond, but he can also enter the pond to swim if he chooses, and he can remove himself from the pond at his will and pleasure. Furthermore, the farmer is not contingent on the pond for his existence, but the pond is contingent on the farmer for its own existence.
Moreover, the farmer has good reason to maintain the pond but sometimes mere men can let things get in the way. My wife has an elderly aunt who is the caretaker of their family farm. There is a farm pond on the property where we would go fishing as youngsters. Because of her age and health (among other things) the pond has fallen into near disrepair. Because it was not maintained, the dam is nearly completely washed away and now all that remains is a very large mud hole with a creek running through it. Eventually, my father-in-law hopes to repair the dam. The point here is that the Bible tells us God upholds his creation. He maintains it always (Col. 1:17). We can count on him even though we fail.
Since the beginning of time God has upheld time and the universe and He never fails. He is maintaining things and keeping order for us. How awesome! So remember, God doesn’t need a “beginning” because he is not bound by time. He transcends time altogether.
I hope this brings some insight to you and gives you some thinking points when it comes to defending our awesome God.
