16, 17. What must happen before the marriage of the Lamb can take place in heaven?

¹⁶ Once all the 144,000 are in heaven, the final preparations for the marriage of the Lamb can begin. (Rev. 19:9) But something else will happen before that joyous event. Remember, shortly before the remaining ones of the 144,000 are taken to heaven, Gog will attack God’s people. (Ezek. 38:16)

¹⁷ The resulting war of Armageddon will lead to the magnifying of Jehovah’s holy name. (Rev. 16:16) At that time, all goatlike ones “will depart into everlasting cutting-off.” The earth will finally be cleansed of all wickedness, and the great crowd will pass through the final part of the great tribulation. With all preparations completed, the climax of the book of Revelation, the marriage of the Lamb, can take place. (Rev. 21:1-4)d All those surviving on the earth will bask in God’s favor and experience bounteous expressions of his love. What a marriage feast that will be! Do we not look forward to that day with eager expectation?​—Read 2 Peter 3:13.
