Before God created the universe, where was He? What was He doing? Where does He get all this knowledge? I know we are supposed to think (believe) that He created everything. I believe that too! But I cannot stop wondering where did He come from? Who created Him? How can something create itself, and why did He give life to an angel that later rebelled against Him? I mean we suffer because Satan was created. Thank you.
In John 1, the apostle answered your question about the origin of God.
In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of men. (NASB) John 1:1-4
The apostle introduces us to the Word who is Jesus Christ in John 1:14. When the Holy Spirit says that “In the beginning was the Word” He uses a special Greek word for “was” which has the idea of something continuously existing in the past. That is, the Word was existing before the beginning began. Jesus was existing before anything started. The Word was existing before there was the beginning and He was existing with God. But there are not two Gods, there is only one because we are told that the Word was God. In the Greek the phrase “The Word was God” is actually reversed. In the Greek the word order is “God was the Word.” The emphasis is on “God” and tells us that the Word was God completely and totally. He was nothing more and nothing less. The Word was not an angel, a created being, a divine thought, or anything else. He was God totally and completely.
Next we discover that the WORD made everything. Some have taught that only Jesus made the universe, but that is not true since scripture also teaches that God the Father made the universe in Rev. 4:11 and God the Holy Spirit created the universe in Genesis 1:1. Everything that exists was made by the One who was existing before the beginning began.
Then we are given an answer to one of your questions. We are told that “in Him was life.” The word “was” is the same Greek word we saw earlier that means that life was existing in Him continuously in the past. He has always had life existing in Himself. He did not create Himself because He has always existed. Nothing can create something before it was. Nothing can create itself before it was. How can anything create itself? The Greek word “was” tells us that He has always existed. He was not created. he had no beginning
This is what is wonderful about God. He is beyond my wildest imagination. If I could understand Him, then I doubt that He would be God. What was He doing before the beginning? We are not told, so we do not know. Where does He get all this knowledge? We do not know, since we are not God. Why did He create angels and allow sin into the world? God never tells us, but we know that God decided to let us have an ability to make choices. It appears that God wants our love to be our choice. He did not want robots.
John 1:1 tells us that the Word was, is, and will always be God. God is self existing, all knowing, and has created everything. That is a good definition of any being we would call God. We can rejoice that we do not understand God. Otherwise, He would not be God. If I could understand such a being then He would probably not be God. Praise the Lord.
