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
The question still remains whether they will see God with their eyes open and by means of these bodily eyes. For, of course, if spiritual eyes in a spiritual body can see no better than our present eyes can see, then it will certainly be impossible for even spiritual eyes to behold God. If the spiritual realm, without material form, circumscribed by no place but everywhere wholly present, is to be visible to the eyes of a spiritual body, then those eyes will most certainly have to have a power altogether unlike the power of any eyes on earth. It is true that we say that God is in heaven and on earth, and he himself through a prophet says, “I fill heaven and earth.” But this does not mean that in heaven we shall say that God has one part there and another part on earth. For he is entirely in heaven, and he is entirely on earth. He is in both simultaneously, not merely successively—which is utterly impossible in the case of any material substance.
