Luke Chapter 15 is one of the clearest pictures of God’s mercy in all of Scripture.

The chapter begins with tax collectors and sinners drawing near to hear Jesus, while the Pharisees and scribes complain that He receives sinners and eats with them. Jesus answers that complaint with three parables: the lost sheep, the lost coin, and the lost son.

All three parables make the same point.

God does not merely tolerate repentant sinners.

He rejoices over them.

This connects well with Luke Ch14, where Jesus spoke of the banquet and the unexpected people brought in by grace. In Luke 15, we see the heart behind that grace.

The Parable of the Lost Sheep

Jesus says that if a man has a hundred sheep and loses one, he leaves the ninety-nine in the open country and goes after the one that is lost until he finds it.

Then, when he finds it, he lays it on his shoulders rejoicing.

That image is important.

The sheep does not rescue itself.

The shepherd seeks.

The shepherd finds.

The shepherd carries.

From a Christian Reformed lens, this is a beautiful picture of grace. The lost are not found because they were strong enough to return on their own. They are found because the Shepherd comes after them.

This also connects with John Ch10, where Jesus is the Good Shepherd who knows His sheep and lays down His life for them.

Jesus says there will be more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance. That last phrase is exposing the Pharisees’ mindset. They think they are the ninety-nine. They do not see their own need.

The Parable of the Lost Coin

Then Jesus tells of a woman who has ten silver coins and loses one. She lights a lamp, sweeps the house, and seeks diligently until she finds it. When she does, she calls her friends and neighbors to rejoice with her.

Again, the point is joy.

Heaven rejoices over repentance.

The coin, like the sheep, does not recover itself. The one who values it seeks it carefully.

This parable adds something gentle and searching. What is lost may look small to others, but not to the one who loves it. The woman does not say, “I still have nine.” She searches until the lost one is found.

That is how Jesus answers the complaint that He receives sinners.

He receives them because He seeks the lost.

The Parable of the Lost Son

Then comes the longest and most famous parable.

A younger son asks for his share of the inheritance, which is already a shameful request. He wants the father’s goods without the father himself. He leaves for a far country and wastes everything in reckless living. When famine comes, he is reduced to feeding pigs and longing to eat their food.

Then he comes to himself.

He decides to return and confess: “Father, I have sinned against heaven and before you. I am no longer worthy to be called your son.”

That is repentance.

He does not excuse himself.

He does not negotiate.

He comes back empty.

But before he can finish everything he planned to say, the father sees him while he is still far off, feels compassion, runs to him, embraces him, and kisses him.

That is one of the most beautiful moments in Scripture.

The father is not cold.

He is not reluctant.

He is full of compassion.

He restores the son with the best robe, a ring, sandals, and a feast. “For this my son was dead, and is alive again; he was lost, and is found.”

That is the Gospel.

The sinner returns in repentance.

The Father receives in mercy.

The joy is loud.

The Older Brother

But the parable does not end there.

The older brother is angry. He has stayed outwardly obedient, but he resents the father’s mercy. He will not go in. He speaks of the younger brother with contempt and of his own service with self-righteousness.

This is Jesus’ answer to the Pharisees and scribes.

They are like the older brother.

They do not rejoice that sinners are received. They are offended by grace.

The father goes out to him too and pleads with him. He says, “Son, you are always with me, and all that is mine is yours. It was fitting to celebrate and be glad.”

That ending is powerful because Jesus leaves the story open. Will the older brother come in? The Pharisees are being asked the same question.

Will they rejoice in grace?

Or will they cling to pride?

The Message of Luke Chapter 15

Luke Chapter 15 shows the heart of God toward repentant sinners.

The shepherd seeks the lost sheep.

The woman searches for the lost coin.

The father runs to the returning son.

And heaven rejoices.

From a Christian Reformed lens, this chapter shows both repentance and sovereign grace. The lost do repent. The son truly returns. But the deeper comfort is that God is the One who seeks, receives, and rejoices.

This chapter also warns us about the older brother spirit. It is possible to be outwardly near and inwardly far. It is possible to resent grace while thinking yourself righteous.

Luke 15 calls sinners to come home.

And it calls religious people to rejoice when grace is given.

The lost are found.

The dead are made alive.

And the Father’s house is full of joy.
