Of old hast thou laid the foundation of the earth: and the heavens are the work of thy hands.
God is self-existent selfhood. Novation, the church father, said, “God has no origin.” Just those four words, “God has no origin,” would be an education to the average person. Origin, you see, is a creature word. Everything came from somewhere. One of the questions that every child asks is, “Where did I come from?”…
Everything has an origin. When you hear a bird sing, you know that once that bird was packed in a tiny little egg. It came from somewhere; it came from an egg. Where did the egg come from? It came from another little bird. And that bird came from another little egg, and that egg came from another bird, and so on, back, back, back to the heart of God, when God said, “Let the heavens bring forth, let the earth bring forth, let the dry land appear,” as it says in Genesis 1.
Origin is a creature word. The trees had an origin, space had an origin, the mountains, the seas—all things have an origin. But when you come back to God, you come back to the One who has no origin. He is the Cause of all things, the uncaused Cause. AOGII021
I worship You today, Lord, as the great Creator, the uncaused Cause behind my very existence. Amen. 
102:25 This verse emphasizes that Yahweh is the one who rightfully reigns over everything, for He created it.
102:25 Of old. God existed before His work of creation. The author of Hebrews applies vv. 25–27 to Christ (Heb. 1:10–12). There the argument is that however great the angels are considered, they are created and not eternal. But Christ, the second person of the Trinity, exists through all eternity.
