What kind of man, being publicly humiliated and facing certain death, claims to be King of every nation and over all the Earth?
One who is.
Don’t get it twisted: Jesus was quoting Psalm 22 when he cried out from the cross, “”Eli, Eli, lema sabachthani?” that is, “My God, my God, why have you forsaken me?” (Matthew 27:46 ESV). Why? Because he wanted us to know who he was.
“All the ends of the earth shall remember and turn to the Lord, and all the families of the nations shall worship before you. For kingship belongs to the Lord, and he rules over the nations. All the prosperous of the earth eat and worship; before him shall bow all who go down to the dust, even the one who could not keep himself alive. Posterity shall serve him; it shall be told of the Lord to the coming generation; they shall come and proclaim his righteousness to a people yet unborn, that he has done it.” (Psalm 22:27-31 ESV)
What did he do?
“But he was wounded for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his stripes we are healed.” (Isaiah 53:5)
Jesus Christ “has done it” and, “it is finished.” (John 19:30)
