Two Adams and Two Brides Genesis 2:18-25 with Ephesians 5:22-33 God ordains marriage for the good of humanity – and to reveal a Gospel mystery. 1. Marriage is appointed for covenant companionship. (Gen. 2:18-22; Eph. 5:22-27). 2. Marriage is the uniting of the husband and the wife as one flesh – to reflect the mystery of Christ’s union with His bride, the church. (Gen. 2:23-25; Ephesians 5:31-32).
