Isaiah 6:1 “In the year that King Uzziah died, I saw the Lord, high and exalted, seated on a throne; and the train of his robe filled the temple.”
King Ussiah reigned for fifty-two years.  His death must have caused worry and anxiety for many in Israel.  It can be tempting to depend on current leadership in running the affairs of the nation.  Isaiah likely went to the temple to pray and ask for God’s help.  God gave Isaiah just what he needed, a glimpse of the King of Kings.  In Isaiah’s time, kings would wear robes. The back of the robe would hang down and sweep across the floor symbolizing majesty and honor.  The custom was, that the conquering king would have portions of the defeated king's robe cut and sown onto his own robe.  The longer the train of his robe, the greater it symbolized his conquests. 
God allowed Isaiah to see that the train of His robe filled the temple!  It symbolized that he had defeated every enemy.  Isaiah may have come into the temple anxious, but what a relief to be reminded that God has the victory.  Every trial, tribulation, and trouble is no match for our conquering King of Kings.
