In this story Jesus' purpose was to teach us a message and this message was about love, compassion and forgiveness. In this story the son was lost and he couldn't find himself. He makes mistakes and sins until he comes back to his father hungry. His father sees him but he feels compassion and he loves his son even though he has sinned he forgives him because he had found himself because he was lost but now he is found.
Samuel RyanLuke 15:11-32 The Prodigal Son
The youngest son asks for his portion of his fathers money.
Father may I have my portion of your owning now
Soon after he got his fathers money he went away to another land and there he wasted his money.
He becomes hungry and he decides to go to his father and confess that he has sinned.
I have sinned against heaven I am not worthy to be the son of my father
He goes to his father but his father is not angry but he is happy that his son is home.
It is ok son you have found yourself we shall celebrate for this reason you are home now
I am sorry father I have sinned against heaven i am not worthy to be your son
We shall celebrate because my son was dead but now he is alive
They celebrated as the youngest son was now home as he was lost but now he was found.
