The dispensation of the Kingdom describes the period of 1,000 years in Revelation 20 in which Christ rules on earth from David’s throne. It is the period in time that the Jews were looking forward to during Christ’s first advent and even His disciples were confused about. This period of time is known as the Millennial Kingdom.
During the Millennial Kingdom Satan is bound and unable to tempt anyone. As Jesus reigns as King of Kings and Lord of Lords nature is restored to the harmony in which it was intended. Christians who died during the tribulation are brought resurrected and reign with Christ along previously resurrected and raptured saints.
The tribulation causes Israel to realize that they have missed the coming of their Messiah and it is during this time that all Israel becomes saved as Paul writes about in Romans 11. The Millennial Kingdom is the fulfillment of prophecies to Israel. They finally lay hold of all of the land that God promised them in Numbers 34. Even more importantly is that the Davidic Covenant is fulfilled as David’s throne is established eternally as Christ is reigns from David’s throne.
The Davidic Covenant establishes not only a long line of succession beginning with David’s son Solomon but David’s line was never broken. David wanted to build a temple for the Lord but he was told that his son Solomon would be the one to build the temple. David was also promised that even if Solomon sinned, God would not remove him from the throne as He had Saul. David’s kingly line remains intact for the sake of David. This does not mean that Solomon would go unpunished for his sins as we are told in 2 Samuel 7:15.
We know that David is a descendant of David. What many don’t realize is how literal this prophecy is. Both Mary and Joseph are descendants of David, Joseph through Solomon and Mary through David’s son Nathan. As Joseph’s legal son, Jesus carried on the kingly line of Solomon as God had promised that the kingship would not be removed from Solomon. But Solomon is not an ancestor of Jesus (being that Jesus is genetically only Mary’s son). David’s line was carried on genetically and held the rights to the throne. Solomon’s line continued to hold the rights to the Davidic throne through Jesus but he was not a physical ancestor of Him.
Isaiah 65:18-25 describes the conditions of the Kingdom. Death will be held back as one who dies at the age of 100 will be considered just a youth. War and disaster will not cause people to lose houses or crops that they planted. Even nature itself will be restored to tranquility as the lion lay down with the lamb. Despite conditions that are much better than exist today, perfection is still not attained on earth.
Despite the reign of Christ and Satan being bound, there will still be sin in the Millennial Kingdom. It is man’s nature and there will be rebellion even at this time. Jesus will deal with sin swiftly however. At the end of the Millennium, Satan will be unbound for a short time and he will deceive people once again. As he gathers followers together, fire comes down from heaven and consumes them. Then Satan is cast into the lake of fire. All of this is according to Revelation 20:7-10.
