Leonard Ravenhill ( 1907-1994), a British evangelist, once said, "The greatest miracle God can do today is to take an unholy man out of an unholy world, make that man holy, then put him back into that unholy world and keep him holy in it.
"This seems to be what God did to Isaiah when he called him to speak to His people.
   Around the time of the death of Uzziah, one of Judah's more successful Kings, Isaiah had a vision of God. The prophet saw Him as the true King of the universe, sitting on a lofty throne. In the vision, Isaiah saw seraphim worshiping God with a hymn that praised His holiness, majesty, and glory.
   Isaiah's vision of God led to a true vision of himself as unholy and broken before God." Woe is me, for I am undone!"
