“Who can even begin to appreciate what this royal marriage means? Who can comprehend the riches of this glorious grace? Christ, the rich and divine bridegroom, marries this poor, wicked whore, redeems her from all of her evil, and adorns her with all of his goodness. It is now impossible for her sins to destroy her, for they are laid on Christ and swallowed up by him. She has her righteousness in Christ, her husband, which she now can boast is her very own… through our marriage all that is his is mine and all this is mine is his..[she] says… ‘my beloved is mine and I am his’”Like the angel says: "Blessed are those who are invited to the marriage supper of the Lamb."
And the church is very much invited, she's the bride.
