"The kingdom of the world of our Lord and of his Christ is come, and he shall reign for ever and ever." Revelation 11 15
When God creates the heavens and the earth, he entrusts to Adam dominion over all creatures. But by disobeying God, man disqualifies himself as the administrator of God over his creation. He receives the sentence of death ; The ground itself is cursed, and the whole creation is subject to vanity, the inability to attain a goal (Romans 8:20).
God would not be God if he renounced what he foresaw! He gives Abraham promises of blessing to all nations. Then he announces to David the future arrival of a royalty of grace and glory (2 Sam. 7). David understands that the Lord speaks not only of his immediate descendant, but of a permanent royal dynasty (2 Sam. 7:19, 29). Finally, when the time comes, God sends His own Son, in whom He fully finds His pleasure.
It is he, their Savior and Messiah, whom the Jews reject, he the heir of the promises made to Abraham and the heir to the throne of Jerusalem announced to David. Jesus could claim his own rights in order to establish his royal glory: did not he say to his disciples that "all things were delivered to him by his Father" (Matthew 11:27) ? On the contrary, he rejoices in the fact that his Father has found good to reveal his thoughts to the small and the humble. Yet he knows that he must die so that divine grace spreads over all nations. Neither the sufferings of his path of humiliation, nor those of the cross will deviate him from his devotion.
It is to this man crucified, but now victorious and risen, that all authority has been given in heaven and on earth. He sits on the heavenly throne, at the right hand of God ; He expects to have his Bride, the Church, near him. Then he will return to where he was crucified, and he will establish his reign for the glory of God alone and the blessing of all the earth.
"When he shall have abolished all power, all authority, and all power", he will hand over this kingdom to God the Father (1 Cor 15:24). It will be the end of his government of the world and, for all the elect, "the entrance into the eternal kingdom of our Lord and Savior Jesus Christ" (2 Pet. 1:11). From then on he will reign "for ever and ever", that is, for eternity.
