1. The Artist’s First Painting

Years ago a seasoned missionary in China befriended a talented young Chinese artist. Through their friendship the young artist became a Christian. He said to the missionary, “I best internalize truth by painting it. Tell me how to paint the Christian faith.” The missionary opened his Bible to Luke 15 and said, “Paint the Parable of the Prodigal Son. If you can paint this, you will have the essence of the Christian faith.”

The artist went to work. His first painting showed the Prodigal trudging down the road, head bowed, clothes ragged, shoulders slumped — the picture of remorse. So far, so good. But then he painted the Father. The Father was standing at the front gate. His arms were folded across his chest. His face was stern. He looked down the road at the returning son with an expression that said, I told you so.

The missionary studied the painting and said gently, “Technically, this is beautiful. But you have missed the main message of the parable.” The artist asked, “How so?” The missionary answered, “The Father should not be standing at the gate with folded arms. The Father should be running. The whole parable turns on one thing — what God is like. He is anxious to love, quick to forgive, eager to reconcile. He runs.”

That conversation is our entire unit in miniature. A parable has one main point. Miss the main point and every detail you paint will sit slightly wrong on the canvas. Get the main point right and even the smallest detail will preach.

2. What a Parable Is

The Greek word parabolé literally means to throw alongside. Jesus would take a familiar earthly scene — a farmer sowing, a woman sweeping, a king holding a wedding feast — and throw it alongside a spiritual truth so the truth could be seen by familiar light. A parable is a short story drawn from ordinary life that carries one central spiritual lesson.

Notice three things in that definition. Short story: the parable is a narrative, not a paragraph of doctrine. Ordinary life: the characters are farmers and shepherds and merchants and children, not angels and dragons. One central lesson: the parable is built around a principal point, not a code where every detail hides a separate doctrine. As this unit will show, context and Jesus's own explanations sometimes mean more than one detail carries real weight — but that weight always serves the parable's main thrust; it is never a license to mine each detail for a hidden meaning of its own.

3. The Difference Between Parable and Allegory

A parable makes one comparison. An allegory makes many. In an allegory, every detail stands for something else: this character is virtue, that character is vice, the road is life, the river is baptism, the trees are nations. Pilgrim’s Progress is an allegory; Bunyan tells us so. Christ’s parables are not.

For more than a thousand years, faithful Christian teachers treated Jesus’ parables as allegories, with disastrous results. Augustine’s reading of the Good Samaritan is the classic case. He took every detail and assigned it a symbol. The traveler was Adam. Jerusalem was paradise. Jericho was the moon — standing for mortality. The robbers were Satan and his angels. The wounds were sin. The priest was the Mosaic law. The Levite was the Old Testament prophets. The Samaritan was Christ Himself. The donkey was Christ’s body. The inn was the church. The innkeeper was the apostle Paul. The two coins were the two testaments. The Samaritan’s promise to return was the Second Coming.

Every detail symbolized something. The reading is ingenious. It is also wrong. Jesus told the parable in answer to a single question from a lawyer: And who is my neighbor? The whole parable answers one question: your neighbor is anyone who needs your mercy, no matter their race or religion. Augustine, by allegorizing, smothered Jesus’ central point under a pile of symbols. He stopped hearing what Jesus actually said.

4. Finding the Principal Point

Here is the rule for every parable you ever preach. Find the one central point Jesus is making. Build your sermon on that point. Treat every other detail in the story as scenery — the furniture of the room, not the message of the room. The scenery is real. It is not random. But it is not symbolic, and the parable does not depend on it carrying secondary meanings.

How do you find the central point? Three signals usually settle it. First, what question is Jesus answering? The Good Samaritan answers, Who is my neighbor? The Lost Sheep answers, Why is Jesus eating with sinners? The Vineyard Workers answers, Are the late-coming workers really equal to us? Second, who is in the audience? The Prodigal Son was told to grumbling Pharisees who resented the company Jesus kept — so the elder brother in the story is the audience caught in the mirror. Third, what is the climax of the parable? The line that the whole story is building toward usually carries the main point. In the Prodigal Son, the climax is the Father running. The whole parable is about that running.

5. The Artist’s Second Painting

The Chinese artist took the missionary’s correction and went back to his easel. He painted the parable again. The Prodigal looked the same — stooped, broken, walking home in shame. But this time the Father was different. The Father was running. His robes flapped in the wind. His face was full of joy and relief. And then the missionary noticed something strange. The Father’s shoes did not match. One shoe was red. The other was blue.

The missionary asked about the shoes. The artist explained, “The Father is so overjoyed to see his son coming home, so anxious to welcome him, that he grabs the two nearest shoes and runs out the door. It does not matter that they do not match. All that matters is that his son was lost and now is found.” That is what a parable rightly read looks like. One central point. The details serve the point.

6. The Buddhist Prodigal — Same Plot, Opposite Point

Buddhism has a parable that sounds almost the same as Jesus’. In the Lotus of Perfect Law, a son leaves his father’s house. He wastes years in misery. He returns in rags. But here the story takes a very different turn. The father recognizes the son; the son does not recognize the father. The father tells his servants to clean the son up — but does not reveal his identity. He gives the son humble work to do. He waits to see whether the son will become worthy. Only when the son has earned a better human nature, broken his old habits, and proven himself does the father finally reveal who he is and welcome the son as heir.

Same plot. Opposite central point. The Buddhist parable teaches that the prodigal must earn his way back home, step by step, before grace can be offered. Jesus’ parable teaches the exact opposite. The Father runs while the son is still a great way off. The robe, the ring, and the shoes come before any confession the son has time to finish. Grace precedes earning. The whole story turns on it.

Now here is the warning. A pastor who allegorizes Jesus’ parable — who turns every detail into a moral lesson the son must perform — will end up preaching the Buddhist version while quoting the Christian one. The plot looks the same. The point becomes the opposite. The cure for that is to lock down the one central point first, and let every detail serve it.

7. Three More Parables, One Central Point Each

Try the rule on three other parables you will preach often.

The Sower (Mark 4). Four soils. Four results. One central point: the condition of the heart determines what happens when the Word is preached. Do not preach four separate sermons on four kinds of soil. Preach one sermon on whether the listener will receive the seed. The four soils are scenery serving that point.

The Vineyard Workers (Matthew 20). Workers hired at different hours all paid the same wage at the end of the day. Do not preach this as a lesson in labor economics. It is not about fair wages. The central point is God’s generosity is not constrained by human bookkeeping. The parable comforts those who came to Christ late and rebukes those who think early arrival gives them a higher claim.

The Persistent Widow (Luke 18). A widow keeps coming back to an unjust judge until he grants her request. Do not allegorize the widow as the church and the judge as God. The point is not that God resembles an unjust judge. The point is the opposite: if even an unjust judge will yield to persistent pleading, how much more will a righteous God hear the persistent prayers of His own? The judge is scenery; persistence in prayer is the heart of the parable.

8. When Details Do Matter

There is one exception to the rule, and it is an important one. When Jesus Himself explains a detail of a parable, that detail is no longer scenery — it is the Lord’s authorized symbol. In Mark 4 Jesus interprets the Sower for His disciples. He tells them the seed is the Word of God, the path is the hardened hearer, the rocky ground is the shallow hearer, the thorns are worldly cares, and the good soil is the receiving heart. Those interpretations are not the allegorizer’s invention; they are the Author’s authorized commentary. Use them.

When Jesus does not tell us what a detail represents, we do not get to decide for Him. The fatted calf in the Prodigal Son is not the Lord’s Supper, however cleverly it can be made to fit. The two coins in the Good Samaritan are not the two testaments. The widow’s judge is not the Father. Silence from the Author means scenery, not symbol.

9. Practical Method for Preaching a Parable

Five steps will keep your parable sermon honest. Read the parable in its setting — the question being asked, the audience being addressed, the chapter in which it sits. State the central point in one sentence — if you cannot write it on a single line, you have not yet found it. Test the central point against the climax of the story — the most emotional or surprising line in the parable usually carries the weight. Build the sermon on that central point — not on every detail in turn. Use the details as illustration, not as separate doctrines.

A parable preached this way will burn through your congregation the way Jesus meant it to. A parable allegorized will impress them with your cleverness for ten minutes and feed them nothing for the week. Choose the burning one.

10. Paint the Father Running

Henri Nouwen once spent two hours in the Hermitage in St. Petersburg standing before Rembrandt’s painting of the Prodigal Son. As the daylight outside shifted, the painting shifted with it — different details rising into the light at different angles of the sun. Nouwen wrote, There were as many paintings in the Prodigal Son as there were changes in the day.

A great parable is like that. It has many facets. Many details. Many angles from which to admire it. But it has only one central light source. Find that source and every detail glows where it sits. Lose that source and the painting goes dark.

Pastor, when you preach a parable, paint the Father running. Paint the question being answered. Paint the single light Jesus shone into the room. The mismatched shoes will take care of themselves.
