What is the best song on your play list? For Solomon it was a song that celebrated the joys of marital/romantic/erotic love (Song of Solomon 1:1).
There are no celebratory songs, poems, or positive instructions in Scripture concerning erotic same-sex relationships. The celebratory, joyful, musical, and instructive words of Scripture are reserved for that male/female union, established by God, in the Garden of Eden. For the married couple (Adam and Eve) their relationship with one another would surpass their relationships with all others (parents, children, animals).
Marriage, from the beginning, was designed to be a unique, exclusive, and priority companionship between a man and a woman for a lifetime. Marriage is a "bone of my bones, flesh of my flesh" kind of relationship.
Yet, as Genesis chapter three makes clear, marriage is fallen and in need of redemption. The redemption of marriage is found in the gospel of Jesus Christ.
The best song on Solomon's I-Pod is one that honors God in his provision of romantic-erotic-marital love. When God made Eve, Adam said, "at last." He had looked around at all of the livestock, birds, and beasts--but there was "not found a helper fit for him" (Genesis 2:20). But when God made Eve, Adam said, "This at last is bone of my bones and flesh of my flesh . . ." (23).
The best song in Solomon's collection celebrates God's gift of man and woman in a leave-and-cleave relationship, designed for intimacy. From Genesis chapter three forward, marriage is fallen and in need of redemption. However, redemption is supplied through the gospel of Jesus Christ. Now marriage can positively display the love of Christ for his people.
Solomon knew the impact of sin and the challenges of relationships (Ecclesiastes 2:8, 7:25ff, Proverbs 1-7). He saw death as a bitter experience but even worse than death is the woman whose heart and hands are one big trap. The man who pleases God escapes the trap but the fool walks right in and the net is pulled (Ecclesiastes 7:25ff, Proverbs 1-7). Solomon traces the problems of male/female relationships all the way back to Genesis. He writes, "See, this alone I found, that God made man upright but they have sought out many schemes" (7:28).
Even the best of marriages is wrought with problems. Since the fall folks have been scheming many things, resulting in much trouble.
In Song of Solomon we are shown the more excellent way; the closest thing post-fall to the pre-fall situation. With the whole of Scripture we know that, through Christ, a joyful marriage is not only expected, but also possible.
One of the great remedies to a culture, that is increasingly hostile to biblical marriage, is a godly man and a godly woman who are intoxicated with one another because of the gospel of Jesus Christ.
So with that, Solomon's song opens with these words, "Let him kiss me with the kisses of his mouth"(1:1).
