"The forgiveness of God is gratuitous liberation from guilt. Paradoxically, the conviction of personal sinfulness becomes the occasion of encounter with the merciful love of the redeeming God. "There will be more rejoicing in heaven over one sinner repenting..." (Luke 15:7). In his brokenness, the repentant prodigal knew an intimacy with his father that his sinless, self-righteous brother would never know."
