In some religions people believe their god was created. Others believe their god used to be human like we are and became a god. But no one created the one true God because He is the Creator of everything.
In Isaiah 43:10 God said, “Before me no God was formed, nor will there be one after me.” In Isaiah 44:6 God said “I am the first and the last. Apart from me there is no God.” Between Isaiah 43 and Isaiah 50 that thought is repeated 7 times. Our God is called The Eternal One for that reason. He had no beginning and will have no end.
Deuteronomy 22:27 says that God is eternal. In Micah 5:2 we’re told about the origins of the Messiah. The literal Hebrew reads that they were from “the days of eternity”. The same Hebrew word is used in both passages.
Rabbinical scholars state that the particular way in which the very first letter of the Bible was formed in ancient manuscripts indicates that it’s impossible to know exactly what went on before Genesis 1:1. The Bible neither explains nor justifies God’s presence but from the very beginning man’s understanding has been that He’s an eternal being, without beginning or end.
When you translate the Hebrew name for God, it means the Existing One. In other words, He always has existed and He always will exist. In Deut. 33:27 He’s called the Eternal God, and in Rev. 1:4 He’s the one who is, and who was, and who is to come. He is the Alpha and the Omega, the First and the Last, the Beginning and the End (Rev. 22:13)
“For by Him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created by Him and for Him” (Colossians 1:16).
If God were a created being He could not accomplish much of anything He set out to do. Baker’s Evangelical dictionary defines the providence of God as, “the sovereign, divine superintendence of all things, guiding them toward their divinely predetermined end in a way that is consistent with their created nature, all to the glory and praise of God.”
I believe this is best summarized in a comment God had Isaiah make on His behalf.
“I make known the end from the beginning, from ancient times what is still to come. I say: My purpose will stand and I will do all that I please … What I have said, that will I bring about. What I have planned, that will I do” (Isaiah 46:10-11).
To me the most amazing thing about this is that God will accomplish all that He has determined to do without depriving us of our power of choice. This is what Baker’s meant by the phrase “in a way that is consistent with their created nature.” Only One who is not bound by the constraints of time could do this. Existing outside time itself means God had never been created, but has always been.
