Biblical Foundations: Relational Beings
Based on being physical, sexual beings, we are necessarily relational beings. “It is not good for the man to be alone” (Genesis 2:18). We are made to love. In some mysterious way, we mirror God’s capacity to be one and at the same time three (the doctrine of the Trinity) in our capacity to be separate people and yet united in marriage. In fact, when we combine the creational declaration that “a man will leave his father and mother and be united to his wife, and they will become one flesh” (Genesis 2:24) with the promise of Jesus that “where two or three come together in my name, there I am with them” (Matthew 18:20; see also the discussion of abiding in Christ in John 15), we find a wonderful parallel—in Christian marriage, three (husband, wife, Christ) become one. In some mysterious way, the glue for this blessed union is the husband and wife’s sexual union. Sexuality in general (including our distinction as male and female, and our inclination to love and feel sexual longing) and sexual intercourse in particular were made good by God for His purposes and our good.
