I would purport that it was not the prodigal son’s request to obtain his inheritance early OR even that he squandered it all. Rather it was that upon receiving his inheritance, the younger son went far away from his father’s house to live for himself; and by doing so, he effectively severed all relationship with his father. Therefore we see that the true sin of the prodigal son was that he quantified his sonship in terms of the sum of money to which he was entitled by birthright and failed to recognize the true value of his sonship – the relationship with his father.
Following Christ’s pattern involves removing all sense of self-entitlement and surrendering the right to your own life. We must rid ourselves of the fleshly instinct to self-serve, self-preserve, self-exalt, self-protect, self-defend, self-sustain, self-obtain, self-fulfill, self-determine, and self-reign. Only then can we begin the incredible journey of learning to hear the voice of God and respond in humble obedience. Furthermore, unentitled love is the only weapon powerful enough to defeat the principalities of darkness and transform a human heart into the true likeness of God.
What did Jesus do in response to his equality with God? He laid down his right to be God. Jesus was the only person truly entitled to equality with God, and yet He chose to separate Himself from that reality by literally dying to Himself and thus denying His own right to exert His Godlike power and authority. Our Lord traded His divine entitlement for the will to die. Jesus’ death was a fulfillment of the true character of God, a tangible way to tell the world that the true divine instinct does not rise towards power and preservation but denies the tempting urge to grasp at it. God sent the person of Jesus to be the complete and perfect imprint of His own self-denying identity.
