God is everywhere by His presence and by His power, seeing all, ruling all things. He is also present in His creation by His essence. We know that the entire soul is in every single part of my body at one and the same time. In a somewhat analogous manner God is in every tiny atom of His creation, upholding it in being. He is present in the hills and rocks and rivers, giving them the being they possess and preserving them. He is present in the animals, the birds, the fishes of the sea, giving them not only being but also irrational life.
"All things," writes St. Paul to the Colossians, "were created by Him and in Him, and He is before all and by Him all things consist." We speak of the "consistency" of an overcoat when we mean that quality in it which keeps the parts together. We complain of the lack of "consistency" in cement if it has not that adhesiveness which is necessary for the wall we are building. Now, in creation there is a presence of God, by His essence, which corresponds to this quality of consistency in a piece of material or a bucket of cement. It is He Who keeps things together; every single atom depends absolutely on His sustaining hands.
A realization of faith of this allpervading presence of God by His essence forces us at once to our knees in adoration and reverence. To remember that He always sees me is to preserve an antidote against sinning in His sight. To recognize that His divine Providence rules all things is to foster a most lively trust in accepting His rulings when I cannot see why. To be deeply impressed with the fact that His hands uphold all things, keep them in existence, that in a fly that dashes itself against the windowpane no less than in an angel, He is totally and, from this precise angle, equally present, is a theme for wonder and admiration. "O the depth of the riches of the wisdom and of the knowledge of God! How incomprehensible arc His judgments and how unsearchable His ways! Who hath known the mind of the Lord or who hath been His counselor?"
