The Return Of The King Of Kings

The Lord is and always has been the King of all kings and the Lord of all lords. He reigns over heaven and earth. And yet when He returns from heaven, the fullness of that reign will be made manifest to all. He calls us His servant to occupy until He comes. The outline of the sermon is as follows:
I. When did the Lord begin to reign?
II. What will His return be like?
III. What must we do in the meantime?
