So the youngest son gets the money and the older brother gets the farm. And off the younger brother goes. What he does, of course, is he spends it all—blows it all—on wild living. When he finally is in want and working, slopping hogs for a farmer and wishing that he could eat what he’s feeding the pigs, he can’t stand it. When he finally comes to himself he says, “You know, I’ve got to do something. How many hired servants of my father’s are there who have bread enough to spare and I’m perishing here with hunger? I know what I’m going to do.”
Almost every preacher makes this the boy’s repentance. It’s not his repentance. This is just one more dumb plan for his life. He says, “I will go to my father and I will say, ‘Father, I’ve sinned against heaven and before you.’” That’s true. He got that one right. “And I’m no longer worthy to be called your son.” Score two. He gets that one right. But the next thing he says is dead wrong. He says, “Make me one of your hired servants.” He knows—he thinks he knows—he can’t go back as a dead son, and therefore he says, “I will now go back as somebody who can earn my father’s favor again.
What happens next is that the father is now sitting on the front porch of the farm house. He’s sitting there and he sees the Prodigal, the younger boy, coming down the road from far away. He sees him coming. What does he do? He rushes off the porch, runs a half mile down the road, throws his arms around the boy’s neck and kisses him.
Now, this is all that Jesus does with this scene. The fascinating thing in this parable is that in the whole parable the father never says one single word to the Prodigal Son. Jesus makes the embrace, the kiss, do the whole story of saying, “I have found my son.” The fascinating thing also is that when the father embraces the boy who has come home from wasting his life, the boy never gets his confession out of his mouth until after the kiss, until after the embrace.
Nobody can earn forgiveness. The Prodigal knows he’s a dead son. He can’t come home as a son, and yet in his father’s arms he rises from the dead and then he is able to come to his father’s side.
