If God existed from the beginning, then who created God?
Numerous Bible passages testify that the Godhead (i.e., Father, Son, Spirit) is eternal and without beginning and existed before all created things:
Notice He is called the “eternal” God. The word eternal in Greek means “age-long" or forever. God was never not in existence. Furthermore, God is the Creator of all things, so He existed before all things in Creation:
The beginning of Creation, God and His Son (i.e., the Word) were already in existence.
The first letter in the Greek alphabet is alpha and the last letter is omega. Therefore, the Lord is saying symbolically that He was before everything else and He is after everything else. Again, He was never not in existence.
