The Sermon contrasts two ways of being spiritually lost—the younger son’s open rebellion and the older son’s self-righteous religion—through Jesus’ parable of the two lost sons in Luke 15. Phillip Bethancourt shows that while one child runs from the Father by breaking the rules and the other by keeping them to earn favor, both are rescued by a prodigal God whose extravagant grace runs to meet repentant sinners, restores them as sons and daughters, and invites families of prodigals to wait on the “front porch” with persistent love, truth, and hope.
