Revelation 19:7-9 (NKJV) 

7- Let us be glad and rejoice and give Him glory, for the marriage of the Lamb has come, and His wife has made herself ready.” 

8- And to her it was granted to be arrayed in fine linen, clean and bright, for the fine linen is the righteous acts of the saints.

9- Then he said to me, “Write: ‘Blessed are those who are called to the marriage supper of the Lamb!’ ” And he said to me, “These are the true sayings of God.”
