Good Teacher, What Must I Do?” — Lessons from the Rich Young Ruler (Luke 18)

 Picture a young man who has done everything right. Good family, good job, respected at church, no scandals. He's the one parents hold up as an example. One day he spots Jesus, runs up, and drops to his knees right there in the road. Then he asks the biggest question there is: "Good Teacher, what must I do to inherit eternal life?"

You'd expect the story to end with a testimony. It doesn't. It ends with a man walking away with his head down.

Luke 18:18–30 is a hard passage, and I think it's meant to be. It's tough to read it honestly without asking, "Is that me?" So let's go through it slowly.

A man who had everything

Luke calls him a ruler, and a few verses later says he was very rich. Matthew adds that he was young (Matthew 19:20), and Mark says he ran to Jesus and knelt in front of him (Mark 10:17). Put those together and you get someone wealthy, powerful, sincere and eager. Nobody dragged him there. He wasn't trying to trap Jesus the way some of the religious leaders did. He wanted an answer.

And yet something nagged at him. Why else would a man with that much still ask what he lacked? Money had made his life comfortable, but it hadn't settled his heart. He had status and no certainty. A lot of us know that feeling. You can hit every goal you set and still wake up some mornings sensing that something is missing.

Wanting a good life isn't wrong. Most of us are working toward a better job, a home, a safe future for our kids, and God cares about all of that. But this story reminds us that a full bank account and a full soul are two different things.

"Why do you call me good?"

Jesus' first reply is a surprise. He doesn't welcome the man. He asks, "Why do you call me good? No one is good except God alone" (v. 19).

Is Jesus saying He isn't good? No. He's slowing the man down. "Good Teacher" was a polite title, the kind of thing you'd say to anyone you respected. Jesus won't let it stay polite. If only God is truly good, then either the man is paying a hollow compliment or he's saying more than he realizes.

It's easy to do the same thing. We call Jesus good, wise, inspiring. We sing that He is Lord. Then Monday arrives and our money, our schedule and our plans carry on as though we're the ones in charge. Admiring Jesus costs nothing. Calling Him Lord costs everything, and He knows the difference.

What must I do?

Listen to how the man puts it: what must I do? In his mind, eternal life is something you earn, like a certificate at the end of a long course. Be good enough, keep enough rules, and you qualify.

Plenty of us were raised on that idea, even if nobody said it out loud. We fast so God will answer. We give so God will bless. We stay away from certain things so He won't be angry. None of those practices is bad. But when they turn into a ladder we climb to earn God's favor, we've drifted from the gospel.

Jesus meets him where he is and points to the commandments: no adultery, no murder, no stealing, no false witness, honor your father and mother (v. 20). The man answers without blinking: "All these I have kept since I was a boy" (v. 21). I don't think he was lying. By any outside measure he was probably a good man. But Jesus wasn't judging by outside measures.

The one thing

Then comes the line that changes the whole conversation. "You still lack one thing. Sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me" (v. 22).

Mark gives us a detail that's easy to miss: "Jesus looked at him and loved him" (Mark 10:21). That matters. This wasn't a trap or a put-down. It was love, and it was precise. Sometimes the kindest thing God does is put His finger on the one area we've been guarding.

Notice too that Jesus didn't say this to everyone. Zacchaeus gave away half of what he owned and Jesus said salvation had come to his house (Luke 19:8–9). Plenty of godly people in Scripture were wealthy. So this isn't a rule that money is evil or that being poor is holy. It's a diagnosis for one particular man. Jesus found the exact thing that had a grip on his heart. For him it was wealth. For someone else it might be a relationship, a reputation, a career, a talent, an old grudge.

The command to sell wasn't really about money. It was about who was Lord. The man had kept the commandments about how we treat people, but the first one had quietly slipped: "You shall have no other gods before me." His riches had taken a seat that belonged to God. And whatever we can't release when He asks, we don't really own. It owns us.

He walked away sad

Luke says it plainly: "When he heard this, he became very sad, because he was very wealthy" (v. 23).

He didn't argue or storm off. He just left, grieving. He had run to Jesus asking about eternal life, and now he walked away from it because the price touched the thing he loved most. Of everyone Jesus invited to follow Him in the Gospels, he's the only one we're told said no.

What stands out is how quiet it is. There's no dramatic fall, only a man who couldn't open his hands. I wonder how many of us are sad believers in the same way, holding Jesus in one hand and our favorite thing in the other. We want the blessings of the Kingdom without handing over the throne. It's exhausting, and it doesn't produce joy.

The camel and the needle

As the man leaves, Jesus tells the people around Him, "How hard it is for the rich to enter the kingdom of God! Indeed, it is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God" (vv. 24–25).

That's deliberate exaggeration, a picture of something humanly impossible. Wealth gives us a false sense of safety. When money can fix most of your problems, it gets easy to forget you need God at all. And this isn't only about the rich. Paul warns that "those who want to get rich fall into temptation and a trap" (1 Timothy 6:9). Someone with very little can be owned by money just as completely if their heart lives there.

The disciples are stunned. "Who then can be saved?" they ask. Jesus answers with one of the most hopeful lines in the Gospels: "What is impossible with man is possible with God" (v. 27).

That's the gospel in a sentence. The man asked what he could do, and the honest answer is that he can't do enough. Salvation has to be done for him. That's why Jesus came: to live the life we couldn't live, die the death we deserved, and rise again so that eternal life is a gift, not a wage (Ephesians 2:8–9).

What you give up, and what you get

Peter, never shy, blurts out what everyone is thinking: "We have left all we had to follow you!" (v. 28). In other words, Lord, what about us?

Jesus gives a generous answer. Anyone who has given up home or family for the sake of God's kingdom, He says, will "fail to receive many times as much in this age, and in the age to come eternal life" (vv. 29–30). The young man held on to his wealth and lost both the treasure and the Teacher. The disciples let go and gained more than they imagined. That isn't a promise that giving always makes you rich. It does mean nobody who loses something for Christ ends up a loser.

What this means for us

A few things stay with me from this passage.

Sincerity isn't surrender. The man was earnest, respectful and religious, and he still walked away. You can be sincere on Sunday and still be holding something back.

Good behavior can't save us. He had kept the commandments and still lacked life. No amount of church attendance, giving or clean living replaces a heart handed over to Christ.

Jesus asks about the thing we hold tightest. It's worth sitting quietly and asking, "Father, what am I gripping that You're asking me to release?" It might be a business, a relationship, a plan, a comfortable life. Money itself isn't the enemy. It can feed people, support missions and bless whole communities. The trouble starts when it sits on the throne, so hold it with open hands.

And the invitation at the end matters most. The command to sell was followed by "Then come, follow me." Jesus wasn't after his poverty. He wanted him close. Every surrender is really an invitation to know Him better.

Finally, if you feel stuck, if there's something you know He's asked for and you just can't let go, don't despair. The One who can thread a camel through a needle can soften a stubborn heart. Ask Him for the grace, and mean it.

Don't walk away sad

We live in anxious times. Prices climb, jobs feel shaky, and it's natural to chase security. God cares about your needs, and working hard is no sin. But this story asks a searching question: is God the source of my life, or just an add-on? Do I come to Jesus as Lord, or as a consultant I check with when it suits me?

Some of us have been praying for a breakthrough while clinging to the very thing He asked us to release. Some of us are waiting for the next level and ignoring one simple instruction. Quick obedience isn't a cliché. Often it's the door.

If you're thinking you don't have much to surrender, remember the problem was never the size of his bank account. It was where his heart sat. Every one of us has something we're tempted to put ahead of Christ, and the Holy Spirit is gentle but honest. Ask Him to show you.

The saddest line in the story isn't the camel. It's the quiet one: "He became very sad." He stood face to face with Life itself and left because the price felt too high. That doesn't have to be your story. Jesus is still looking at people with love and still saying, "Come, follow me."

So maybe the better question isn't "What must I do?" but "Lord, what do You want from me, and will You help me give it?"

May we never walk away sad. May we follow Him gladly, the One who left all to come save us.
