Again, this is a philosophical approach to the question of whether or not there is a God. This argument is presented in philosophy in a general way; is there a God? Not, is there a specific being from any one religion. The Cosmological Argument for God is the answer to the question; where did all of this (everything contained in our universe; space/time, energy, matter, etc…) come from?
The basic idea is this; nothing comes from nothing. If there was ever absolutely nothing, nothing could ever come into being; therefore there had to be something. This something must be transcendent. It must not be bound by space/time, since space/time is the very thing that had a beginning, that had to come from something.
This is why the Cosmological Argument is sometimes referred to as the “First-Cause” Argument. The first cause is God. Also, a similar title for God; the Unmoved Mover comes up as well. The universe is in motion…to have energy there needs to be “motion.” Nothing can begin to move unless acted upon by a force…so, there has to be something to act to get everything moving. You wind up, through a series of logical steps at God, Who is moved by no other (“unmoved”). If you want to dig more into this from both a philosophical perspective, and a theological one, St. Thomas’ Five Ways are a good starting point.
These things point at the logical conclusion of the self-existence of God. Many skeptics, at this point, ask; Well, who created God, and where did He come from? This question shows a basic lack of understanding the philosophical arguments here.
One simplistic way to explain it is this; Every event (and effect) must have a cause and every created thing must have a creator. God is neither an event (nor an effect), not a created thing; therefore has no need of a cause nor a creator. God has no beginning, since that first “thing” would be transcendent, or outside of time. If there is no time, there is no “beginning” only self existence.
Now, does the Bible back this idea up? Absolutely.
First, you have God as the Creator of all; the originator of all things. Secondly, we have His wonderfully descriptive title of Himself; I AM that I AM.
Exodus 3:14 And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. 15 And God said moreover unto Moses, Thus shalt thou say unto the children of Israel, The LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me unto you: this is my name for ever, and this is my memorial unto all generations.
God reveals truth in His names, and He is very clear here; He is I AM; eternally self-existent…He also clearly tells Who He is in relation to Moses, so that he can relate to God in a more human fashion; The LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob. God does not depend on anything or anyone else for existence unlike everything else.
This is yet another case where logic and reason points directly at the fact that a God does indeed exist and He is The God of Abraham, Isaac, and Jacob, and that makes Him the Christian God. Christ Himself alluded to His divine title, and the Jewish listeners understood Him quite plainly:
John 8:57 Then said the Jews unto him, Thou art not yet fifty years old, and hast thou seen Abraham? 58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
What did the hearers do? Picked up rocks to stone Him to death. Jesus was indeed existent prior to Abraham, even as He was in their midst. At that point in time, not only was He present with those people, He was also, at the same time, present before Abraham was. He also was the Creator;
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 The same was in the beginning with God. 3 All things were made by him; and without him was not any thing made that was made.
Just further support for the Cosmological Argument pointing at the Christian God…and also support for the triune nature of God.
Again, as a remind, if you are taking a philosophy course this argument is presented for the general idea of a God. But, you can see that the Bible not only backs this argument up, it also points directly at The One and only God; The God of Abraham, Isaac, and Jacob.
