Marriage: The Mystery of Christ and the Church is a Reformed pastor's instruction and exhortation to married couples, especially young married couples, with the purpose that they glorify God in their marriages and enjoy the bliss of this blessed communion of life. Although this book's contention that marriage is an unbreakable bond for life gets the most attention today, Marriage is a mainly positive explanation and application of the Bible's teaching about marriage in all of its aspects.

The marriage of Christ and the church provides us with a goal toward which we press in our marriages. We strive to pattern our marriages after it. We struggle to reflect in our earthly marriages the heavenly one between Christ, the bridegroom, and the church, his bride. This is the glory and beauty of marriage.
