Isaiah 6:6-8

New Century Version

⁶ One of the heavenly creatures used a pair of tongs to take a hot coal from the altar. Then he flew to me with the hot coal in his hand. ⁷ The creature touched my mouth with the hot coal and said, “Look, your guilt is taken away, because this hot coal has touched your lips. Your sin is taken away.”

⁸ Then I heard the Lord’s voice, saying, “Whom can I send? Who will go for us?”

So I said, “Here I am. Send me!”
