As Jesus was entering the city his followers were declaring him king, Luke 19:
38 “Blessed is the king who comes in the name of the Lord!”[a]
“Peace in heaven and glory in the highest!”
Also at Rev 1:5 the writer’s prolog to the 7 congregations he says 5 and from Jesus Christ, who is the faithful witness, the firstborn from the dead, and the ruler of the kings of the earth.
And here is an unexpected thing Jesus says about his kingship, he's so loving. Luke 19:27New International Version (NIV)
27 But those enemies of mine who did not want me to be king over them—bring them here and kill them in front of me.’”
I'll bet there are more scriptures of Jesus saying things we would be shock to read, know of any?
