In this parable, there are two sons: the younger and the older. The younger son was the Rebellious son, and the older son was the Religious son. Which son are you?
The truth is both sons were lost – yes, one left and one stayed at home. The younger was unrighteous and the older was self-righteous. Neither were right with God!
Both sons were in need of God’s grace, just like me and you. This grace can only come from the Son telling the story, the Redeeming Son – Jesus Christ!
