Can any hide himself in secret places that I shall not see him?
says the LORD.
Do not I fill heaven and earth?
says the LORD.
All Commentaries on Jeremiah 23:24 Go To Jeremiah 23
Augustine of Hippo
AD 430
Therefore, God is poured forth in all things. He says by the prophet, “I fill heaven and earth,” and, as I quoted a short time before of his wisdom, “He reaches from end to end mightily and orders all things sweetly.” It is likewise written, “the Spirit of the Lord filled the whole world,” and one of the psalms has these words addressed to him: “Where shall I go from your Spirit, or where shall I flee from your face? If I ascend up into heaven, you are there. If I descend into hell, you are there.”
Yet God so permeates all things as to be not a quality of the world but the very creative substance of the world, ruling the world without labor, sustaining it without effort. Nevertheless, he is not distributed through space in a physical sense so that half of him should be in half of the world and half in the other half of it. He is wholly present in all of it in such a way as to be wholly in heaven alone and wholly in the earth alone, and wholly in heaven and earth together; not confined in any place, but wholly in himself everywhere.
