ANSWER: Who exactly is the bride of Christ who will marry the "the Lamb" in Revelation 19? The person or entity that he will marry is the church of God, which is composed of truly repentant and faithful believers. Revelation records great rejoicing in heaven when the Kingdom of God takes control of the world, in the form of the Lord's Second Coming to the earth, and the wedding of the saints is revealed.
|6. And I heard a voice like that of a great multitude, and like the sound of many waters, and the sound of mighty thunderings, saying, "Hallelujah! For the Lord God Almighty has reigned. 7. Let us be glad and shout with joy; and let us give glory to Him; for the marriage of the Lamb (Christ) has come, and His wife (the bride) has made herself ready." 8. And it was granted to her that she should be clothed in fine linen, pure and bright; for the fine linen is the righteousness of the saints (Revelation 19:6 - 8, HBFV throughout)|
As the true bridegroom, He is not only prepared himself for the marriage but also has cleansed and prepared the bride for the glorious wedding. Apostle Paul, in the book of Ephesians, alludes to the mystery of this relationship by making an analogy between a human-based marriage and the yet-future marriage of Christ and those who are part of the first resurrection.
|23. For the husband is the head of the wife, even as Christ is the Head of the church; and He is the Savior of the body . . . in the same way also let wives be subject to their own husbands in everything . . . 31. For this reason shall a man leave his father and mother, and shall be joined to his wife; and the two shall be one flesh. 32. This is a great mystery; but I am speaking in respect to Christ and the church (Ephesians 5:23 - 24, 31 - 32).|
Your second question concerns the parable of the ten virgins found in Matthew 25 and its relationship to the wedding mentioned in Revelation. The bridegroom of the parable represents Jesus. The ten maidens or virgins (Revelation 4:4) represent all those whom are truly called to salvation who are still ALIVE when he returns to this earth to take over the reins of government. There are, of course, others throughout history who have been called to salvation who will also be resurrected.
Five virgins are considered wise and the other five are foolish. The lamp oil represents God’s Holy Spirit. The wise took or had a sufficient amount of oil (his character) evident in their lives, whereas the foolish did not. Having a sufficient amount of oil are indicative of those true Christians today who are walking with the Eternal on a daily basis and have an active, ongoing relationship with him. They are in training to become kings and priests under Christ at his Second Coming.
When the Lord returns the five foolish virgins will not be ready to "marry" him and attend the wedding supper. These believers were so lackadaisical that they spiritually were not ready to marry the bridegroom. The wise virgins, however, WILL be ready and will reign with him for a thousand years (Revelation 20:6).
One last interesting thing to note is that the great city of God, the New Jerusalem, where Christians will live forever, is also called the bride of Christ (Revelation 21:9 - 10).
