Jesus is also considered a prince or king. The King of Kings, and Lord of Lords. That is not His spiritual title. That is His earthly role. His spiritual title is Messiah. While the death on the Cross was physical is was the spiritual obedience to God. Being Messiah was the relationship between Son and Father. Jesus was still King while living on earth in the obedient spiritual role as Messiah. Jesus just never physically fulfilled the Kingship while on earth, that He was physically born into, as the son of Mary, a man.
So Daniel phrased it the Prince/King to come. But that role has never been enacted. Even though Jesus has all authority in heaven and on earth, Jesus has yet to physically reign as King on the earth. That is the point many leave out of their interpretation of Daniel 9. What if you read the verse like this:
"And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined."
Who are these people? You all still claim Jesus is King/Prince, even while failing to call it a physical role on physical earth. The on earth part is still coming.
"Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times."
They are still the people of the Messiah to come. Daniel told you the Messiah was the Prince. Jesus is both Messiah and Prince. These verses declare that fact. Jesus has still to come and fulfill the physical role as King. Many will declare, "not so. Jesus is spiritually king." Does that mean the president is only spiritually president as a spiritual representative, and never has to put in the physical work as President? Jesus is currently not the physical king of the earth, because at the 7th Trumpet it is declared that all kingdoms will physically be placed under Jesus as King. That means Jesus is physically on earth to take over that physical role.
"And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever."
Does the verse have to specifically say that Jesus is physically Prince/King, when it already declares Jesus is Lord and Messiah/Christ? If they are not His kingdoms now, how can you say Jesus is King physically over them? Being King is a physical role like being the President of the US. President and King is not a spiritual title, but a physical role, by a physical human.
Jesus is a physical King through His physical father David. That is not a spiritual title, because David is human and not God the Father. Jesus is Messiah through His Father God, not because of His father David. Jesus is not King because He is God. Jesus is Lord because He is God. So the Prince/King aspect can only be physical through His physical father David.
