Isaiah 6:5-8

I said, “There is no hope for me! I am doomed because every word that passes my lips is sinful, and I live among a people whose every word is sinful. And yet, with my own eyes, I have seen the King, the LORD Almighty!” Then one of the creatures flew down to me, carrying a burning coal that he had taken from the altar with a pair of tongs. He touched my lips with the burning coal and said, “This has touched your lips, and now your guilt is gone, and your sins are forgiven.” Then I heard the Lord say, “Whom shall I send? Who will be our messenger?” I answered, “I will go! Send me!”
