From Lutheran Synod Digital Publishing:

In the season of Advent, we look to how Christ comes to his church. Couples are invited to celebrate the beauty of Advent at home, in a way that will also enrich your marriages in Christ.

The devotion book Song of Songs: An Advent Devotional for Couples is based on the longest poem in the Bible, a song between a loving husband and wife, as well as a song between God and his people. This booklet gives daily reading and discussion suggestions for couples to use together, as you eagerly look to the coming of Jesus, your heavenly Bridegroom.
