The prophet Isaiah was caught up into a heavenly worship experience. He saw the Lord Almighty high and lifted up, seated on His throne. He witnessed angels worshipping the Lord in His temple. He heard them calling out to one another about the holiness of God. As a result, the whole place shook and the temple filled with smoke.
The experience crushed Isaiah before God called him. “Woe to me!” he cried. “I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the Lord Almighty” (Isaiah 6:5).
Before blessing comes brokenness, before calling comes crushing. And “woe to me” always comes before “here am I Lord, send me.”
