Acts 5:30 The God of our fathers has raised Jesus, whom you
slew by hanging Him on a tree.  (31) This One God has
exalted to His right hand as Leader and Savior, to give
repentance to Israel and forgiveness of sins.

According to Revelation 1:5, He is the Ruler of the kings of
the earth. In a very real sense, Christ as the Ruler of the
kings dethrones all the kings. Only He is the Ruler.
Furthermore, according to Revelation 19:16, He is the King
of kings and the Lord of lords. As the Ruler, He rules the
entire earth. It may seem that kings and presidents rule the
earth and that the Lord Jesus is not on the throne.
Nevertheless, this One who seems not to be on the throne is
the Ruler of all the enthroned ones. Today the entire world
is under the Lord’s ruling. He is truly the Leader, the
chief Ruler.
