Every believer is HAPPY that Christ is called “Lord of lords, and King of kings” (Rev 17.14) and more emphatically “KING OF KINGS AND LORD OF LORDS” (Rev 19.16). These very Revelation Scriptures necessity other kings on earth in the coming Pure World.
And Revelation provides answers for that:
“And he that overcometh and keepeth my works unto the end, to him will I give power over the nations:” Rev 2.26
“And the nations of them which are saved shall walk in the light of it: and the kings of the earth do bring their glory and honor into it” Rev 21.24
“And they shall bring the glory and honor of the nations into it” Rev 21.26
“…the leaves of the tree were for the healing of the nations” Rev 22.2.
HOLD ON Saints, There’s a glorious future for the Faithful. Amen!
