Isaiah 6:1-8
1 In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple.
2 Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew.
3 And one called to another and said: “Holy, holy, holy is the LORD of hosts; the whole earth is full of his glory!”
4 And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke.
5 And I said: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the LORD of hosts!”
6 Then one of the seraphim flew to me, having in his hand a burning coal that he had taken with tongs from the altar.
7 And he touched my mouth and said: “Behold, this has touched your lips; your guilt is taken away, and your sin atoned for.”
8 And I heard the voice of the Lord saying, “Whom shall I send, and who will go for us?” Then I said, “Here am I! Send me.”
Seraphim, which means “burners;” they burn in love to God, and zeal for his glory against sin. The seraphim showing their faces veiled, declares that they are ready to yield obedience to all God’s commands, though they do not understand the secret reasons of his counsels, government, or promises. All vain-glory, ambition, ignorance, and pride, would be done away by one view of Christ in his glory. This awful vision of the Divine Majesty overwhelmed the prophet with a sense of his own vileness. We are undone if there is not a Mediator between us and this holy God. A glimpse of heavenly glory is enough to convince us that all our righteousnesses are as filthy rags.
