When it comes to gods, deep down everyone is a monotheist. There can be only one. Either God is God, or the individual. All of life is love. Love is constantly being expressed. Man cannot not love. Every bit of existence we have is spent loving, worshipping, something. Yet, fallen men cannot love. In loving themselves, they hate love (John 3:19-20). Men hate light because they love darkness, which is another way of saying that they hate love.
By God’s common grace, and because man is made in God’s image, there is a muted echo of love that the unbeliever may hear and that may resound off and through the unbeliever, but it is always second-hand, always an echo and never the original tune. It is always muted, never amplified. It is always a first-grade crush on your married teacher, never marriage consummated and well aged like a vintage wine. It is like saying that you have tasted wine when a drop, a single drop, fell into your full glass of water. The world’s concept of love is diluted. You could never get intoxicated on it.
Jesus extends the cup of the new covenant, the intoxicating, behavior altering wine of His blood, that we might know love and love. If fallen man loves to hate love, how can he ever love love? Let me give you two answers, which are two ways of saying the same thing: covenant and a heart transplant. Listen carefully to the command, “love the Lord your God.” The context for this command is Deuteronomy, redemption, salvation. God, not because of anything Israel has done, calls a people unto Himself. He enters into covenant with them. And His covenant love gives His people a new heart (Deuteronomy 30:6; Jeremiah 31:31, 33; Ezekiel 36:26-27). A heart that loves Him, that loves His Son, that loves His law, that loves others, that loves His creation—that loves, really loves.
