If I would say to you, what's your most base sin, your worst action of evil, would you come up with something like failure to be grateful to God?
Student
And if a person is truly grateful, he shows it in worship and in service to God.
Teacher
We read in verse 12, as he entered a certain village, he met 10 men who were lepers who stood afar off. Now we know of course, that once you had been diagnosed with leprosy in ancient Israel, you suffered the worst of all possible kinds of quarantines. Not a quarantine that would last a week or two weeks, but it would be a quarantine that would last for the rest of your life, unless by some marvelous means you were cured of that leprosy. You were sentenced to a solitary life, removed from the community, removed from your family, removed from the religious institutions of your day. You were a social pariah. And the only fellowship that you could have with other human beings would be with other lepers. And so there were reasons why lepers gathered together in groups such as this group of 10, because that was the only companionship that they could enjoy was with other miserable human beings. And now as they are outside the village and Jesus approached while they were standing afar off, they lifted up their voices because Jesus was at a distance. And so they shouted out to him, jesus, master, have mercy on us.
Student
And when he saw them, he said to them, go show yourselves to the priests.
Teacher
A citation from the book of Leviticus, where it was the priest who was authorized to make the diagnosis in the first place of leprosy. And if a person were recovering or if it was a false diagnosis, it would take the priests declaration to free them from the quarantine. So Jesus didn't say, be clean, you're healed. He said, go see the priests. Which meant what? This is not an idle mission. It's not a fool's errand. If I tell you to go see the priests, I'm telling you to go check yourselves out and you will be clean.
Student
And so it was that as they went, they were cleansed again.
Teacher
Not when they just first saw Jesus, but after they started on their journey to see the priests. While they were walking along the road.
Student
All of a sudden their fingers are becoming whole, their toes are being healed.
Teacher
And the horrible sores on their body were vanishing. And one leper would say to the other, look at my hand, it's clean. And the other one would say, mine too, it's happening. And they were beyond themselves with joy and excitement as their bodies were being cleansed. With every step they took on their way to the priests.
Student
But one of them, when he saw that he was healed, returned.
Teacher
Imagine 10 lepers in a group watching.
Student
Each other suddenly being made whole. They can't wait to get to the.
Teacher
Priests because they know if they go to the priest and the priests pronounce them clean, then in that moment they can go home again. They can see their wives again, they can embrace their children again, they can go to church again.
Student
So they say, let's go.
Teacher
Hurry up.
Student
And one says, wait a minute. Wait a minute.
Teacher
Wait.
Student
We're clean, aren't we? Yes, it was Jesus who made us clean. We've got all day to see the priests, but first we have to go back and see him and thank him and honor him. The rest of the lepers says, we don't have time for that.
Teacher
The first one says, aren't you grateful? Grateful? How can you not be grateful? I'm sure all 10 of them were grateful. No question that they were grateful. You can't be healed of leprosy like that and not be grateful.
Student
Their hearts were filled with gratitude, but not so filled that they want to detour and have to go back to say thank you.
Teacher
See, beloved, it's one thing to be grateful. It's something altogether to show it, to manifest it, to do. Gratitude, feeling and doing are not the same thing.
Student
If I would say to you, what's.
Teacher
Your most base sin, your worst action of evil? Would you come up with something like failure to be grateful to God?
Student
Hardly.
Teacher
But this is our fundamental problem.
Student
We think that God owes us everything that we receive and much more. And if a person is truly grateful, he shows it, and he shows it in worship and in service to God. This is why we're here. We've been made clean, and we come to give praise, and we come to give thanks. So Jesus answered and said, am I having a problem with my math? Did I not just heal? 10. Where are they?
Teacher
Where are the other nine?
Student
Oh, sir, they're on the way to the priest like you told them. Yes, but you came back to say thank you. You came back to give honor. You came back to praise God. Where are the rest? He's speaking to the man. And the man's still on the ground.
Teacher
And now Jesus said to him, arise, go your way.
Student
Your faith has made you well now. This poor leper was really clean. Do you see it? It's your story. It's my story. How do you show your thanks to Christ? How do you give glory and honor to your Redeemer? That's what we're about.
Teacher
Saying thank you.

Main Theme: The depth and importance of genuine gratitude to God, as illustrated in the biblical story of Jesus healing the 10 lepers (Luke 17:11–19).
This episode centers on the deeper meaning of gratitude in the Christian life, illustrated through the well-known story of Jesus healing the 10 lepers. R.C. Sproul challenges listeners to consider whether their greatest sin might be a failure to show proper gratitude to God, not just to feel it inwardly. The message highlights the difference between feeling grateful and acting on it through worship, service, and giving thanks for God's grace.

On the root of sin:
"Would you come up with something like failure to be grateful to God?"
—R.C. Sproul (00:00)
On the difference between feeling and action:
"It's one thing to be grateful. It's something altogether to show it, to manifest it, to do. Gratitude, feeling and doing are not the same thing."
—R.C. Sproul (05:37)
On the true purpose of worship:
"If a person is truly grateful, he shows it, and he shows it in worship and in service to God. This is why we're here."
—R.C. Sproul (06:21)
On Jesus’ expectation:
"Where are the rest? He's speaking to the man. And the man's still on the ground."
—R.C. Sproul (07:24–07:28)
R.C. Sproul skillfully draws out the heart of the biblical narrative by challenging listeners: being truly grateful means acting on that gratitude through worship, service, and giving thanks—not just feeling thankful. He reframes ingratitude as a deep and overlooked spiritual failing, calling Christians to a life of expressive praise.
Final Reflection:
"How do you show your thanks to Christ? How do you give glory and honor to your Redeemer? That's what we're about. Saying thank you." (07:32–08:04)
