De Moor IV:27: God's Immensity and Omnipresence Proven from Scripture
It is evident from this Definition that our AUTHOR does not speak of the Presence of divine Knowledge and Operations only, but of His Essential Presence. And that in this sense Omnipresence and Immensity coincide, it proven, α. by Express passages of Scripture:
Jeremiah 23:24, 24: In which, 1. God speaks most clearly of Himself with respect to His Essence, saying אֲנִי/I several times. 2. He affirms Himself to be near and afar off at the same time, in such a way that even in the places most far removed, where man sometimes supposes that he has removed himself far from God, He is nevertheless present. 3. In the description of His Presence the Lord joins the earth with heaven, and affirms Himself to be present in both in equal measure.
Psalm 139:7-10: In which again, 1. the Psalmist could hardly speak more expressly of God’s Presence with respect to Essence than he does, saying, שָׁ֣ם אָ֑תָּה, thou art there, and הִנֶּךָּ, behold, thee. He makes mention, not only of God’s hand and right hand working most powerfully, but also of His face, or essential presence. 3. He says that God is not otherwise present in heaven, than in שְּׁאוֹל/Sheol/hell or בְּאַחֲרִ֥ית יָֽם׃, in the uttermost parts of the sea.
Acts 17:27, 28: in which from the present Power of God, whereby we are continually sustained, Paul concludes that God Himself is present to us in these lands.
And so, since, 1. Paul, in this passage, from the operating Power of God concludes His actual Presence with respect to Essence, equally also in the passages cited from Jeremiah and from the book of Psalms from the Essential Presence of God is concluded His Knowledge extended to all hidden things: it follows that God’s Knowledge and operating Power, where divine Omnipresence is treated, are not to be opposed to His Essential Presence, but are to be agreeably conjoined. 2. Since in the passages cited all places are equally conjoined with Heaven, it follows that God either is nowhere Present with respect to Essence, not even in Heaven itself; or, if He is Essentially Present in Heaven, He is also Present in all other places in this manner.
 Jeremiah 23:23, 24: “Am I (אָנִי) a God at hand, saith the Lord, and not a God afar off? Can any hide himself in secret places that I (וַאֲנִי) shall not see him? saith the Lord. Do not I (אֲנִי) fill heaven and earth? saith the Lord.”
 Psalm 139:7-10: “Whither shall I go from thy spirit? or whither shall I flee from thy presence (מִפָּנֶיךָ, from thy face)? If I ascend up into heaven, thou art there (שָׁ֣ם אָ֑תָּה): if I make my bed in hell, behold, thou art there (הִנֶּךָּ). If I take the wings of the morning, and dwell in the uttermost parts of the sea; Even there shall thy hand lead me, and thy right hand shall hold me.”
