The marriage and supper of the Lamb will take place in heaven near the end of the seven years of judgment upon the earth. "When a man hath taken a new wife, he shall not go out to war, neither shall he be charged with any business: but he shall be free at home one year, and shall cheer up his wife which he hath taken." Deut. 24:5.
As Christ presents the Church to Himself (Eph. 5:27), the vaults of heaven will echo with unrestrained praise, worship, and ecstatic joy. Rev. 19:7. "Praise our God, all ye his servants, and ye that fear him, both small and great." Rev. 19:5.
"And I heard as it were the voice of a great multitude, and as the voice of many waters (majesty), and as the voice of mighty thunderings (power), saying, Alleluia; for the Lord God omnipotent reigneth." Rev. 19:6.
"Let us be glad and rejoice, and give honor to him: for the marriage of the Lamb is come, and his wife hath made herself ready. And to her was granted that she should be arrayed in fine linen, clean and white (pure and bright); for the fine linen is the righteousnesses (N.T.) of saints." Rev. 19:7,8. Heaven has never before experienced a time of exceeding joy and bliss as that hour of the marriage of the Lamb.
When the guests, including the Old Testament saints and the martyrs of Rev. 20:4, are present, the marriage supper of the Lamb will take place. "Blessed are they which are called unto the marriage supper of the Lamb." Rev. 19:9.
