Jesus revealed that He is our bridegroom. (Mt 9:14-15)

Mt 9:14 Then came to him the disciples of John, saying, Why do we and the Pharisees fast oft, but thy disciples fast not? 15 And Jesus said unto them, Can the children of the bridechamber mourn, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and then shall they fast.

In the Old Testament, the Israelites are often referred to as virgins. This is what God called the Israelites to do to receive them as God's bride. (Jer 31:4)

Jer 31:4 Again I will build thee, and thou shalt be built, O virgin of Israel: thou shalt again be adorned with thy tabrets, and shalt go forth in the dances of them that make merry.

On that day, God will make the people of Israel and the spiritual people of Israel His bride. (Hos 2:16,19-20)

Hos 2:16 And it shall be at that day, saith the Lord, that thou shalt call me Ishi; and shalt call me no more Baali. 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.

It can be seen that we are getting married in this world to understand Christ, our future bridegroom. (Eph 5:31-32)

Paul was eager to preach the gospel to us so that we could match up with Christ. (2 Cor 11:2)

2 Cor 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 stand as the bride of Christ at the wedding supper of the Lamb on the last day. (Rev 19:7)

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.
