It is important that we correct some of the grossly misinformed ideas that prevail about the Bible's view of the physical universe. It does not assert that humans are the only intelligent and personal beings in the whole sweep of space. On the contrary, Scripture asserts that there are vast multitudes of non-human beings, both intelligent and personal, who inhabit regions that elude the detection of our telescopes and microscopes.
Earth Is The Theater Of The Universe.
First, this insignificant planet is the theater of the universe. Hence, as the angels watch, they do so with intense sympathy and concern, sometimes rejoicing as God's purposes are fulfilled, sometimes saddened as God's purposes are frustrated. The reaction of the demons is exactly the opposite. Angels, then, are engrossed by this spectacle of redemption. These passages, in short, declare that our earth is the object of interest to a host of invisible beings.
