3, 4. (a) How long will Jehovah’s reign by Jesus Christ and the 144,000 actually be? (b) What expression is used for that time period, and how was that reflected in the titles of certain Watch Tower publications?

³ The length of Jehovah’s Kingdom rule by Jesus Christ and his 144,000 glorified disciples was foretold to be a thousand years. Regarding that Thousand Year Reign, the aged apostle John wrote: “I saw thrones, and there were those who sat down on them, and power of judging was given them. Yes, I saw the souls of those executed with the ax for the witness they bore to Jesus and for speaking about God, and those who had worshiped neither the wild beast nor its image and who had not received the mark upon their forehead and upon their hand. And they came to life and ruled as kings with the Christ for a thousand years. (The rest of the dead did not come to life until the thousand years were ended.) This is the first resurrection. Happy and holy is anyone having part in the first resurrection; over these the second death has no authority, but they will be priests of God and of the Christ, and will rule as kings with him for the thousand years.”​—Revelation 20:4-6.

⁴ Since a thousand years is a millennium, that period is called Christ’s Millennial Reign. Those who accept and teach this Bible doctrine are sometimes called millenarians or chiliasts, according to the Greek word for “thousand.” Interestingly, the volumes of Studies in the Scriptures (once published by the Watch Tower Bible and Tract Society) were originally called Millennial Dawn. And the songbook once used by the International Bible Students was entitled Hymns of the Millennial Dawn.

7. What does the Bible indicate about the time and nature of Jesus Christ’s Millennial Reign?

⁷ According to the Scriptures, however, the true Millennial Reign of Jesus Christ is still future. Present-day fulfillment of Bible prophecy shows that it is very close at hand. During the true Millennium, Satan and his demons will actually be abyssed, and Jesus Christ and his 144,000 joint heirs will reign over all mankind without interference from the Devil’s organization. The everlasting blessing of all redeemed mankind, in fulfillment of Jehovah’s covenant with his “friend” Abraham, will begin with the “great crowd,” who will survive the unparalleled “tribulation” with which this wicked system ends. It will extend to the billions of human dead ransomed by “the blood of the Lamb,” Jesus Christ. (James 2:21-23; Revelation 7:1-17; Genesis 12:3; 22:15-18; Matthew 24:21, 22) To this end, these will be resurrected from their death sleep in the memorial tombs to life on earth.​—John 5:28, 29.
