The whole earth is full of his glory

“And one cried unto another, and said, Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory.” - Isaiah 6v3

How could Isaiah go from bemoaning the Israel’s spiritual state to the point where he says “the whole earth is full of His glory?” In chapters 1-5 Isaiah saw the great spiritual wickedness of the land. He says when the king died his focus changed. “I saw the Lord high and lifted up! His glory filled the temple. The seraphim cried holy, holy, holy.”

When that word is used three times in a row like that it is to emphasis the fact, each use of “holy” building on the previous one. Now, it is because the Lord is “holy, holier, holiest” that Isaiah could say – “the whole earth is full of His glory.”
The only thing that changed was Isaiah’s perspective. Man is wicked and vile, he had made a total of mess of things, but the whole earth is still full of God’s glory! Man’s wickedness on the face of the earth does nothing to affect God’s glory. Praise God that even when man’s wickedness seems great God’s glory is still there!
