In the story, we learn about the relationship between a father and his two sons. The plot centers around the younger son who, impatient and greedy, asks his father for his inheritance. The father agrees, but the son wastes his money, eventually becoming homeless and destitute.
In the end, to the son’s great surprise, he is welcomed back into the family by his father and brother. If you’d like to read the Parable of the Lost Son yourself, it appears in Luke 15:11-32.
