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. Isaiah 6:5.
It is not the sight of our sinful heart that humbles us; it is a sight of Jesus Christ. I am undone because mine eyes have seen the King.—Andrew A. Bonar.
