Luke 17: Faith, Forgiveness, and the Coming Kingdom

Jesus teaches his followers about forgiveness, faith, and grateful service, then heals ten lepers and points ahead to the coming of his kingdom.

Coming soon

Luke 17 (WEB)

1 He said to the disciples, “It is impossible that no occasions of stumbling should come, but woe to him through whom they come!

2 It would be better for him if a millstone were hung around his neck, and he were thrown into the sea, rather than that he should cause one of these little ones to stumble.

3 Be careful. If your brother sins against you, rebuke him. If he repents, forgive him.

4 If he sins against you seven times in the day, and seven times returns, saying, ‘I repent,’ you shall forgive him.”

5 The apostles said to the Lord, “Increase our faith.”

6 The Lord said, “If you had faith like a grain of mustard seed, you would tell this sycamore tree, ‘Be uprooted, and be planted in the sea,’ and it would obey you.

7 But who is there among you, having a servant plowing or keeping sheep, that will say, when he comes in from the field, ‘Come immediately and sit down at the table,’

8 and will not rather tell him, ‘Prepare my supper, clothe yourself properly, and serve me, while I eat and drink. Afterward you shall eat and drink’?

9 Does he thank that servant because he did the things that were commanded? I think not.

10 Even so you also, when you have done all the things that are commanded you, say, ‘We are unworthy servants. We have done our duty.’”

11 As he was on his way to Jerusalem, he was passing along the borders of Samaria and Galilee.

12 As he entered into a certain village, ten men who were lepers met him, who stood at a distance.

13 They lifted up their voices, saying, “Jesus, Master, have mercy on us!”

14 When he saw them, he said to them, “Go and show yourselves to the priests.” As they went, they were cleansed.

15 One of them, when he saw that he was healed, turned back, glorifying God with a loud voice.

16 He fell on his face at Jesus’ feet, giving him thanks; and he was a Samaritan.

17 Jesus answered, “Weren’t the ten cleansed? But where are the nine?

18 Were there none found who returned to give glory to God, except this stranger?”

19 Then he said to him, “Get up, and go your way. Your faith has healed you.”

20 Being asked by the Pharisees when God’s Kingdom would come, he answered them, “God’s Kingdom doesn’t come with observation;

21 neither will they say, ‘Look, here!’ or, ‘Look, there!’ for behold, God’s Kingdom is within you.”

22 He said to the disciples, “The days will come, when you will desire to see one of the days of the Son of Man, and you will not see it.

23 They will tell you, ‘Look, here!’ or ‘Look, there!’ Don’t go away, nor follow after them,

24 for as the lightning, when it flashes out of the one part under the sky, shines to the other part under the sky; so will the Son of Man be in his day.

25 But first, he must suffer many things and be rejected by this generation.

26 As it was in the days of Noah, even so will it be also in the days of the Son of Man.

27 They ate, they drank, they married, they were given in marriage, until the day that Noah entered into the ship, and the flood came, and destroyed them all.

28 Likewise, even as it was in the days of Lot: they ate, they drank, they bought, they sold, they planted, they built;

29 but in the day that Lot went out from Sodom, it rained fire and sulfur from the sky, and destroyed them all.

30 It will be the same way in the day that the Son of Man is revealed.

31 In that day, he who will be on the housetop, and his goods in the house, let him not go down to take them away. Let him who is in the field likewise not turn back.

32 Remember Lot’s wife!

33 Whoever seeks to save his life loses it, but whoever loses his life preserves it.

34 I tell you, in that night there will be two people in one bed. The one will be taken, and the other will be left.

35 There will be two grinding grain together. One will be taken, and the other will be left.”

36

37 They, answering, asked him, “Where, Lord?” He said to them, “Where the body is, there will the vultures also be gathered together.”

Summary

Jesus warns his disciples against causing others to stumble and calls them to forgive a brother again and again, even seven times in a day. When they ask for greater faith, he answers that faith the size of a mustard seed is enough, for the issue is the God they trust, not the size of their belief. He likens disciples to servants who simply do their duty without expecting praise. On the way to Jerusalem, ten lepers cry out for mercy and are healed as they go, yet only one, a Samaritan, returns to give thanks and is told his faith has made him well. The chapter closes with teaching about the kingdom of God, which is already among them, and the sudden, unmistakable revealing of the Son of Man, a day for which people must be ready.

Lessons Learned

  • Forgiveness is to be offered freely and repeatedly, flowing from a heart shaped by grace.
  • Even small faith is powerful when it rests in a great and faithful God.
  • Gratitude is the right response to mercy, yet it is easily forgotten.
  • The kingdom of God is present among us in Jesus and will one day be revealed for all to see.
  • We are called to forgive generously and again and again. Jesus says that if a brother sins and repents seven times in a day, 'you shall forgive him' (Luke 17:4, WEB).
  • Faith's strength lies in its object, not its size. Jesus says faith like a grain of mustard seed could uproot a tree (Luke 17:6, WEB), showing that even small trust in God accomplishes much.
  • True service expects no applause. Jesus teaches that after doing all we are commanded we should say, 'We are unworthy servants. We have done our duty' (Luke 17:10, WEB).
  • Mercy received should turn the heart to thanksgiving. Of the ten cleansed, only the Samaritan returned, 'glorifying God with a loud voice' (Luke 17:15, WEB), and Jesus asked where the other nine were.
  • God's kingdom comes quietly now and gloriously later. Jesus says, 'the Kingdom of God is within you' (Luke 17:21, WEB), even as he warns the Son of Man's day will flash like lightning across the sky.
  1. How does Jesus describe the kind of forgiveness his followers should show, and why is it so demanding?
  2. What does Jesus mean when he compares faith to a mustard seed?
  3. Why might only one of the ten healed lepers have returned to give thanks, and what made him different?
  4. What does Jesus teach about the coming of the Son of Man and the need to be ready?
  5. Where in your own life is God inviting you to forgive more freely or to give thanks more readily?
  1. Jesus calls his disciples to forgive a repentant brother even seven times in a single day (Luke 17:3-4). Such forgiveness is demanding because it sets no limit and trusts God rather than keeping a record of wrongs.
  2. Faith the size of a mustard seed can do the seemingly impossible (Luke 17:6). Jesus shifts attention away from the quantity of faith to the power of the God in whom that faith rests.
  3. Ten were cleansed, but only the Samaritan turned back to glorify God and fall at Jesus' feet (Luke 17:15-16). His gratitude marked him out, and Jesus told him his faith had made him well (17:19).
  4. Jesus warns that the Son of Man's day will come suddenly and visibly, like lightning (Luke 17:24), and recalls the days of Noah and Lot. People are to live ready, not clinging to this present life (17:33).
  5. This is a personal application question. Invite members to reflect honestly on where forgiveness or thanksgiving is hard for them. As leader, encourage gentle sharing and point back to the grateful Samaritan, and do not press anyone to share more than they wish.
