“Who has performed and accomplished it, Calling forth the generations from the beginning? ‘I, the LORD, am the first, and with the last. I am He.'” Isaiah 41:4
The “eternal” question is always who created God? When explaining creation to people this is always the question that usually pops up, however the reason this question arrives is because people have the wrong view of God.
God is eternal, he created time, space, and matter. Therefor God is outside of time, he is eternal. This is a concept we as humans have a hard time comprehending. And its natural to have these difficulties understanding since we are bound by time right now.
God reveals to the prophet Isaiah that He is eternal, he is the beginning and the end. Nothing came before God and not will come after him, God is eternal
When I saw Him, I fell at His feet like a dead man. And He placed His right hand on me, saying, “Do not be afraid; I am the first and the last, Revelation 1:17
Jesus revealed himself as eternal also, when he revealed himself to the Apostle John, he identified himself as the first and the last, the same God revealed himself to Isaiah. Are we starting to draw a conclusion here? Just as God revealed himself as “I AM Who I AM”(Exodus 3:14) to Moses which means he is eternal, Jesus revealed himself as the “Great I AM” on several occasions.
“I am the Alpha and the Omega, the first and the last, the beginning and the end.” Revelation 22:13
Jesus is God who became Flesh (John 1:14) The Father , Son , and Holy Spirit all co-exist and are eternal, our God is an eternal God, and because of what Christ did for us on the cross, we can one day live in eternity with him in Jesus name Amen
