The Prodigal God looks at the Parable of the Prodigal Son as a parable about the lostness of both brothers and the heart of God the Father that is revealed towards them both. Keller shows clearly that the parable is a powerful challenge to self-righteous, religious moralists. Both brothers are lost, and the only way back to the father is through his love and grace. This poses a special problem to those who are self-satisfied with their religious practices. Nevertheless, even Pharisees are invited to enter the joy of the feast. The love of the Father invites all to come in. This is only possible because of the life, death, and resurrection of the Lord Jesus Christ. We have all sinned and been cut off from our proper home, but through Christ a new heavens and new earth are being made where a great feast will take place. The only way to gain entrance is through Christ Jesus himself.
