The nature of God is paramount in apologetics, so today we will continue to explore what that nature entails. The article below explains God’s immensity:
Immensity. Along with eternity is the attribute of immensity (nonspatiality). God is not limited in time, nor is he limited in space. In God’s immanence he fills space, but he is not spatial. Only material things exist in space and time, and God is not material. “God is spirit” (John 4:24). As spiritual, God is not material or spatial. It is part of God’s transcendence that he is beyond both time and space.
