What titles will Jesus have when He is enthroned in Jerusalem?

When Jesus is enthroned in Jerusalem and the kingdom is set up, His name shall be called Wonderful, Counsellor, Mighty God, and Everlasting Father. These titles declare His deity, for Scripture presents Him as the Mighty God and the Son given for the world.

Les teaches that when Jesus is on His throne in Jerusalem and the kingdom is set up, the government shall be upon His shoulder, and His name shall be called Wonderful, Counsellor, Mighty God, and Everlasting Father. He notes how these titles ring out in Handel's Messiah. He also contrasts this with liberal theologians who claim Christ was never God, saying Scripture screams that He is God, the Mighty God. The title Everlasting Father is connected to Philip's request, "Show us the Father," and the Son given is in perfect accord with John 3:16.

Isaiah 9:6

For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.

When will the government be upon Jesus' shoulder according to Isaiah?

Isaiah foretells that the government will be upon His shoulder when He is on His throne in Jerusalem and the kingdom is set up. This is the time when the Messiah's reign is established, fulfilling the covenant promises that He would come and be their Messiah.
