In this class, Justin explores the nature of marital love by reviewing Tim Keller's third chapter, "The Essence of Marriage." Keller argues that at the heart of real love is the act of promising and commitment. While any notions of duty and legally binding oneself to another (which are entailed in the making of any covenant) are seen by many today to be restrictive, oppressive and counter-productive to one's self-flourishing, Keller shows that in fact the actions of love lead to greater feelings of love and freedom.
