6:3 “And one called to another and said: ‘Holy, holy, holy is the LORD of hosts; the whole earth is full of his glory.”
Isaiah had a vision in which he saw the Lord sitting on His throne. This entire vision was to impress Isaiah and his listeners with the majesty and glory of God. The Hebrew nation had long thought of God’s glory being in the tabernacle and then the temple. Isaiah gives us a broader picture of God.
God is not the God of a city or a country or a nation but is the God of all the earth. He did not belong to Jerusalem, the city of the temple, or even to Judah, the faithful tribes of Israel. He belonged to all of mankind, and His reign covered the entire earth.
Israel had long had trouble with this concept. They thought God was just their God, and they could treat Him as they wished. They borrowed what they thought were other Gods from the nations around them and served them as well. Idolatry then and now is the result of not believing that God is God of all the earth.
Task for Today: Understand that the triple use of the word ‘holy’ is the writer’s way of saying it to the nth power. The result of that holiness, the glory of God, fills the whole earth. Actually, it goes beyond the earth. There is no place without Him. When you are tempted to worship something else, think about this verse.
