We are married to God, we are meant to reign with Him. To reign with Him we need to do righteous deeds like Virgin Mary.
6 Then I heard what seemed to be the voice of a great multitude,
like the sound of many waters and like the sound of mighty thunderpeals, crying,
“Hallelujah! For the Lord our God the Almighty reigns.
7 Let us rejoice and exult and give him the glory,
for the marriage of the Lamb has come,
and his Bride has made herself ready;
8 it was granted her to be clothed with fine linen, bright and pure”—
for the fine linen is the righteous deeds of the saints.
9 And the angel said to me, “Write this: Blessed are those who are invited to the marriage supper of the Lamb.”Revelation 19:6-9
And he said to me, “These are true words of God.”
