God is in all things...Now since God is very being by His own essence, created being must be his proper effect; as to ignite is the proper effect of fire. Now God causes this effect in things not only when they first begin to be, but as long as they are preserved in being; as light is caused in the air by the sun as long as the air remains illuminated. Therefore as long as a thing has being, God must be present to it...being is innermost in each thing and most fundamentally inherent in all things...Hence it must be that God is in all things, and exists intimately within everything.
He is the God who made the world and everything in it. Since he is Lord of heaven and earth, he doesn’t live in man-made temples, and human hands can’t serve his needs—for he has no needs. He himself gives life and breath to everything...--Thomas Aquinas
His purpose was for the nations to seek after God and perhaps feel their way toward him and find him—though he is not far from any one of us.
For in him we live and move and exist.
--Acts 17.24-28
