Menrov, as a matter of fact, Christ has not started ruling as yet. He will only take over the rulership of the world after the seventh trumpet blast (cf. Rev. 11:14, 15) which points to the future. I have researched it and can demonstrate it by using the Greek words stephanos (laurel wreath) and cornona (crown or diadem) in the book of Revelation.
στέφανος, like the Latin corona, is a crown in the sense of a chaplet, wreath, or garland, the badge of victory in the games, of civic worth, of military valour, of nuptial joy, of festal gladness. The crown worn by the rider of the white horse (Rev. 6:2), however, is clearly a victory wreath and serves to designate victory as the task of this rider. See EDNT.
John continues: “And I saw
the heaven opened, and, look! a white horse. And the one seated upon it is
called Faithful and True, and he judges and carries on war in righteousness.
His eyes are a fiery flame, and upon his head are many diadems” [διαδήματα πολλά, NA28]. John explains what
this means: “He has a name written that no one knows but he himself, And
upon his outer garment, even upon his thigh, he has a name written, King of
kings and Lord of lords.” His status as God’s appointed warrior king is
confirmed by him wearing “many diadems” (Rev. 19:11, 12, 16).
διάδημα (διαδέω, to bind round), the
diadem is the sign of royal status, i.e., the blue band marked with white with
which Persian kings used to bind on the turban or tiara; the kingly ornament
for the head. Rev. 12:3: the dragon has “seven diadems” on its seven heads; 13:1:
the beast has “ten diadems” on its ten horns; 19:12: the rider of the white
horse has “many diadems” on his head. This makes it clear that Christ’s
kingship is superior to that of the dragon and its beast. See EDNT
and Thayer.
