In the Old Testament, Isaiah prophesied that God would welcome us as his bride and rejoice. (Isa 62:4-5, Isa 54:5, Isa 61:10, Ho 2:19-20)
Isa 62:4 Thou shalt no more be termed Forsaken; neither shall thy land any more be termed Desolate: but thou shalt be called Hephzibah, and thy land Beulah: for the Lord delighteth in thee, and thy land shall be married. 5 For as a young man marrieth a virgin, so shall thy sons marry thee: and as the bridegroom rejoiceth over the bride, so shall thy God rejoice over thee.
Isa 54:5 For thy Maker is thine husband; the Lord of hosts is his name; and thy Redeemer the Holy One of Israel; The God of the whole earth shall he be called.
Isa 61:10 I will greatly rejoice in the Lord, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh himself with ornaments, and as a bride adorneth herself with her jewels.
Ho 2:19 And I will betroth thee unto me for ever; yea, I will betroth thee unto me in righteousness, and in judgment, and in lovingkindness, and in mercies. 20 I will even betroth thee unto me in faithfulness: and thou shalt know the Lord.
As the church, we are the bride of Christ. (Eph 5:31)
Eph 5:31 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh.
Paul tried to mediate us to Christ. (2 Corinthians 11:2)
2 Corinthians 11:2 For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ.
We will participate as the bride of Christ at the wedding supper of the Lamb. (Rev 19:7, Rev 21:9)
Rev 19:7 Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife hath made herself ready.
Rev 21:9 And there came unto me one of the seven angels which had the seven vials full of the seven last plagues, and talked with me, saying, Come hither, I will shew thee the bride, the Lamb's wife.
