What does it mean that God is omniscient?
God being omniscient means He is all-knowing. As the context illustrates, He has not lost sight of any one of the trillions of stars. Nothing escapes His knowledge or awareness. He knows all things, and His understanding is complete and universal.
Les teaches that God is omniscient, meaning He is all-knowing. In the context, after noting trillions of stars, the question is asked whether God has lost sight of any one of them; the answer is not a one. Les then connects this to God's omnipresence—you cannot go anywhere that God is not there, even to the deepest hell or highest heavens. He also describes God as infinite, beyond anything we can comprehend, and as just and righteous, never treating anyone unfairly.
