Revelation 19:7-8

7Let us rejoice and shout for joy! Let us give Him glory and honor, for the marriage of the Lamb has come [at last] and His bride (the redeemed) has prepared herself.”

8She has been permitted to dress in fine linen, dazzling white and clean—for the fine linen signifies the righteous acts of the saints [the ethical conduct, personal integrity, moral courage, and godly character of believers].
