Messianic promises from the Psalms are applied to the present reign of Jesus who possesses all authority in Heaven and on Earth. 

Jesus has reigned as Sovereign over the Earth since his Death, Resurrection, and Ascension, already, he is seated on the Messianic Throne. Because of his obedience, he is the “Ruler of the Kings of the Earth.” Before his Ascension, he declared that God had bestowed all authority on him – “In Heaven and on Earth.” His authority is without limits and a present reality. Thus, working for competing political entities becomes, at best, a waste of time. Only God’s Kingdom will endure.

When Jesus first appeared in Galilee, he proclaimed the “Kingdom of God” – “Repent, for the kingdom is at hand.” In his ministry, God’s reign had begun to invade the Earth. But his realm was and remains of an entirely different nature than the political systems of the present fallen age. Moreover, on more than one occasion, Jesus refused THAT kind of political power, especially when it was offered by Satan who tempted him with sovereignty over “all the kingdoms of the world.”
