Isaiah the prophet looked forward to Christ. Even though Isaiah was a prophet, he knew he was not perfect. He shared his vision in Isaiah 6: I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple. Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts.
