Song of Solomon: Passionate Marital Love

This last wisdom books seems to not belong with the others. But it does. The wisdom it offers is pursued by many, the wisdom of beautiful marital love. The woman is as unabashedly praising of her husband as he is of her. They enjoy one another physically.
Over and over again is the reminder to not awaken love until it so desires. Do it God's way. Wait on Him and enjoy a godly spouse and all the pleasures that relationship entails. Also note that it's jealousy is "as unyielding as the grave." A love relationship with faithfulness and trust in one another is extremely powerful and profound.
