In the beginning, God…. GE 1.1
For all eternity, before time itself, God was all alone. There was no heaven, no earth, no angels, no people – only God – Father, Son, and Holy Spirit. He had no beginning.
This is mind-boggling. God had no beginning. He always was. We simply can’t grasp or understand that, because everything else in this universe, everything else we know and see and have anything to do with had a beginning. But God had no beginning. For eternity God was “self-contained, self-sufficient, self-satisfied; in need of nothing.” -AW Pink, The Attributes of God
“God was completely and infinitely joyful in and of himself. He had no needs. He wasn’t lonely. He wasn’t bored or unfulfilled. He didn’t need our worship. He didn’t create the universe out of any need. He just did it to manifest his glory. All God created added nothing to him in his essential glory” (Pink).
In his self-existence, God didn’t have to create anything. He did it for his own good pleasure.
In him we have obtained an inheritance, having been predestined according to the purpose of him who works all things according to the counsel of his will (EPH 1.11)
God doesn’t need anything from us. He doesn’t need our worship. He didn’t need all the glory he would get by redeeming us. He does all things according to his own purpose for his own glory.
