At this wonderful ceremony, the Bride will be given a very special privilege—that of being able to wear fine, clean, white linen. This raiment is so much more beautiful, important, and meaningful than even the loveliest of today's physical wedding gowns.
A study of fine, clean, white linen in the Bible reveals that this fabric (or more correctly, a spiritual version of it) is the material worn by angels. It was also worn by royalty and by God's priests, and it was also used extensively in the construction of the Tabernacle. At the marriage of the Lamb, the children of God who make up His Bride will become worthy to wear this fine, clean, white linen because, as well as becoming like angels (as Jesus describes their state in Matthew 22:30), they will become kings, priests, and pillars in God's Temple. Here in Revelation 19:8, fine linen is described as symbolic of "the righteous acts of the saints."
