The Prodigal God by Timothy Keller is a modern day look at Jesus’ parable of the Prodigal’s son. The older son is looked upon as a moralistic do-right church attending type person who disdains the younger worldly thrill seeking brother.
Keller chooses to focus on the older brother, and his attitudes towards those outside his moralistic self-righteous compass.
Keller holds that we need not only repent of sin, but also of our righteousness. Only in God’s extravagant grace is found true righteousness and relationship; true for both brothers. Trying to simply live righteously apart from Christ is on self-righteousness alone is an exercise in god-making self-exaltation.
