Is God present everywhere, and how is He present in the world?
Yes, God is omnipresent: He is present in all places and at all times. Because God is pure spirit and not confined by space or physical boundaries, He is present everywhere in three distinct ways: by His power (all things are subject to His rule), by His presence (all things are open and bare before His gaze), and by His essence (He sustains everything in being at every moment). In a special way, God is present by grace in the souls of the just, and uniquely, sacramentally, and substantially in the Most Holy Eucharist.
