Jeremiah 23:24

It was by this same divine creative force, which knows not what it is to be made but only how to make, that roundness was given to the eye, to the apple and to other objects that are by nature round and that we see all about, taking on their form with no extrinsic cause but by the intrinsic power of the Creator, who said, "Do I not fill heaven and earth?" and whose wisdom "reaches from end to end mightily and orders all things sweetly."

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.

"And He that sent me is with me." He had already said this also before, but of this important point He is constantly reminding them, "He sent me," and "He is with me." If then, O Lord, He is with Thee, not so much hath the One been sent by the other, but ye Both have come. And yet, while Both are together, One was sent, the Other was the sender; for incarnation is a sending, and the incarnation itself belongs only to the Son and not to the Father. The Father therefore sent the Son, but did not withdraw from the Son. For it was not that the Father was absent from the place to which He sent the Son. For where is not the Maker of all things? Where is He not, who said, "I fill heaven and earth"? But perhaps the Father is everywhere, and the Son not so? Listen to the evangelist: "He was in this world, and the world was made by Him." Therefore said He, "He that sent me," by whose power as Father I am incarnate, "is with me, hath not left me."
