On Facebook once I saw a person asking what one word we would use to describe God. Talk about a tough order. It would be easier to sum up the known universe in one word, because of course God is infinitely more complex than His universe.
Is God love? Of course God is loving to his human creations, but He is capable of hatred. Intense hatred. Hatred of sin and anything evil. Calling Him love would be much too simplistic, though He is that.
Is God power? He is all-powerful, all-knowing, and present everywhere. “And everywhere that man can be, Thou God, art present there,” as it goes in the old hymn, I Sing the Mighty Power of God.
Still omniscient, omnipotent, and omnipresent as God is, none of these are His chief glory. His crowning glory–the only characteristic repeated three times in the Bible is “Holy.”
When Isaiah saw the LORD lifted up in a vision, the blazing angels called seraphs worship God by saying over and over to each other, “Holy, holy, holy is the LORD God almighty. Heaven and earth are full of His glory.”
