In the book of Revelation it tells about the wedding of Christ and His Church.  Christ is the Lamb and true Christians as a group are His bride. Those who attend are greatly blessed.

Revelation 19:

4 Then the twenty-four elders and the four living beings fell down and worshiped God, who was sitting on the throne. They cried out, “Amen! Praise the Lord!”

5 And from the throne came a voice that said,

“Praise our God,
all his servants,
all who fear him,
from the least to the greatest.”
6 Then I heard again what sounded like the shout of a vast crowd or the roar of mighty ocean waves or the crash of loud thunder:

“Praise the Lord!
For the Lord our God, the Almighty, reigns.
7 Let us be glad and rejoice,
and let us give honor to him.
For the time has come for the wedding feast of the Lamb,
and his bride has prepared herself.
8 She has been given the finest of pure white linen to wear.”
For the fine linen represents the good deeds of God’s holy people.
9 And the angel said to me, “Write this: Blessed are those who are invited to the wedding feast of the Lamb.” And he added, “These are true words that come from God.”

10 Then I fell down at his feet to worship him, but he said, “No, don’t worship me. I am a servant of God, just like you and your brothers and sisters who testify about their faith in Jesus. Worship only God. For the essence of prophecy is to give a clear witness for Jesus.
