Consider Isaiah’s reaction upon hearing the seraphs proclaim Jehovah’s holiness. “Then I said: ‘Woe to me! I am as good as dead, for I am a man of unclean lips, and I live among a people of unclean lips; for my eyes have seen the King, Jehovah of armies himself!’” (Isaiah 6:5) Yes, Jehovah’s infinite holiness reminded Isaiah of how sinful and imperfect he was. Initially, that faithful man was devastated. But Jehovah did not leave him in that state.

¹⁸ A seraph promptly consoled the prophet. How? The mighty spirit flew to the altar, took a coal from it, and touched the coal to Isaiah’s lips. That may sound more painful than comforting. Remember, though, that this was a vision, rich in symbolic meaning. Isaiah, a faithful Jew, well knew that sacrifices were offered daily at the temple altar to make atonement for sins. And the seraph lovingly reminded the prophet that although he was indeed imperfect, “of unclean lips,” he could still come into a clean standing before God.a Jehovah was willing to view an imperfect, sinful man as holy​—at least in a relative sense.​—Isaiah 6:6, 7.
