Faith, Works – and Faith (Luke 17:1–19)

[Hiddenthings]

At first glance, it is not easy to see how this teaching of Jesus connects with the parables that immediately precede it. This portion of Luke’s gospel, containing little overlap with Matthew or Mark can seem like a collection of unrelated sayings. Yet, to assume they are disconnected may be a serious mistake.

Jesus begins with a strong warning about becoming a stumbling block to any of his “little ones.” Here, the term does not refer to children but rather to new, young, or immature disciples (cf. 1 John 2:12–13; John 13:33; Matt. 10:42; Zech. 13:7). How might such stumbling occur? Likely through two main avenues: clumsy handling of personal relationships or unwise, unsympathetic decisions made within the fellowship. The Lord’s severe tone here shows how deeply he valued the preservation of unity and fellowship among his followers.

The hyperbolic image of a person who causes another to stumble being cast into the sea with a massive mule-driven millstone (not a small hand-held one) tied around his neck drives home just how dreadful God’s displeasure is in such situations.

Yet there is another side to this warning. The one who has been offended must be equally cautious, not to make too much of every slight, whether intentional or accidental. Misjudgments do occur, and a thin-skinned believer can become a danger to fellowship by being overly sensitive, even endangering their own spiritual well-being. The believer must remember that God sees all and that, in His time, every injustice and misjudgment will be made right.

Therefore, Jesus warns, “Take heed to yourselves”, guard against an unforgiving spirit.

Peter once asked, “Lord, how often shall my brother sin against me and I forgive him? Up to seven times?” (Matt. 18:21). The Lord’s startling answer there is now reiterated and expanded: “If he repents, forgive him. And if he sins against you seven times in a day, and seven times returns to you, saying, ‘I repent,’ you must forgive him.”

From a human perspective, such repeated repentance might appear insincere or even cynical. Yet Jesus insists his disciples take a man at his word, harboring no suspicion of deceit. After all, what right has one who has been freely and undeservedly forgiven by Almighty God to withhold forgiveness from someone else, however undeserving?

This man is offering a thoughtful and layered interpretation of a passage from Luke’s Gospel, specifically focusing on Jesus’ teaching about stumbling blocks, forgiveness, and spiritual maturity. His main point is that while the sayings in this section of Luke may seem disconnected from the surrounding parables, they are actually deeply unified by a central theme: the preservation of fellowship and the posture of mercy within the community of believers.
Here’s a breakdown of what he’s saying:

Connecting the Dots in Luke’s Gospel
• At first glance, this portion of Luke seems like a string of unrelated sayings.
• But assuming they’re disconnected is a mistake—they’re tied together by Jesus’ concern for how believers treat one another, especially the vulnerable and immature in faith.

Warning Against Causing Others to Stumble
• Jesus warns strongly against being a stumbling block to His “little ones”—interpreted here not as children, but as new or immature disciples.
• Stumbling can happen through poor handling of relationships or unwise decisions in the fellowship.
• The image of a millstone tied around someone’s neck and cast into the sea is meant to show how seriously God views this kind of harm.

Caution for the Offended
• The warning isn’t just for the offender—it’s also for the one who’s been offended.
• Believers must be careful not to overreact to every slight, especially when it’s accidental.
• Being overly sensitive can also damage fellowship and spiritual health.
• Jesus says, “Take heed to yourselves”—guard against bitterness and unforgiveness.

Radical Forgiveness
• Peter’s question about forgiving someone seven times is met with Jesus’ radical command:
“If he sins against you seven times in a day and returns saying, ‘I repent,’ you must forgive him.”
• Even if it seems insincere, Jesus calls His followers to extend grace without suspicion.
• Why? Because we’ve been forgiven freely and undeservedly by God—and we’re called to reflect that mercy.

The Core Message
This teaching isn’t just about forgiveness—it’s about the character of the Kingdom. Jesus is showing that:
• Fellowship must be protected
• Mercy must be extended
• Judgment must be left to God
• And forgiveness must be freely given, even when it stretches us

In short, this man is saying: Don’t underestimate the spiritual weight of how we treat one another. Jesus’ words here are a call to humility, grace, and relational wisdom—not just for the sake of the individual, but for the health of the whole body.

Faith and the Sycamine Tree

One day the apostles pleaded with their Master: “Lord, increase our faith.” But faith in what? If tied to the context, they may have been asking for help to live up to his daunting standards of discipleship.

Another possibility is that they were recalling the rebuke they once received when they failed to heal the epileptic boy during Jesus’ absence after the Transfiguration (Mt 17:19–20). That failure naturally left them longing for greater faith, so they might not let him down again. Yet, Luke 17 and Matthew 17 are not close in sequence, so the link may be less direct.

More likely, it was the parables of Luke 15 and 16, the Prodigal Son, the Unjust Steward, and especially the Rich Man and Lazarus, that struck the Twelve with sobering force.

They were beginning to realize that Jesus was not seeking to reform the old order but to inaugurate a New Creation. The burden of this mission would fall on them, twelve ordinary men who now faced a colossal task against entrenched tradition, prejudice, and the power of the temple establishment. No wonder their faith faltered at such a prospect. It is telling that Luke here calls them “apostles” (v.5), highlighting the weight of the commission soon to rest upon them.

Jesus’ response to their plea was given in parabolic form:

“If you have faith as a grain of mustard seed, you could say to this sycamine tree, ‘Be uprooted and planted in the sea,’ and it would obey you.”

This answer echoes what he told them earlier: “If you have faith as a grain of mustard seed, you shall say to this mountain, ‘Move from here to there,’ and it shall move” (Mt. 17:20). On that earlier occasion, his words reflected the exhilaration of spirit following the vision of Moses, Elijah, and the Shekinah Glory on the mount. But by the time of Luke 17, the growing opposition and weariness of his path had given a more sombre tone to his teaching.

Interpretation

The sycamore (AV) refers to a kind of maple, but the sycamine, the tree Jesus actually mentioned is a type of fig tree. In the Septuagint (LXX), every occurrence of the sycamine clearly points to the fig tree. The symbolism is straightforward. Time and again, Scripture associates the fig tree with the Jewish nation (Jer. 24; Mic. 7:1; Hos. 9:10; Joel 1:7; Hab. 3:17; Mt. 21:19; 24:32; Lk. 13:6; Rev. 6:13).

Jesus seems to have anticipated that one of the greatest challenges awaiting his apostles would be the very trial he himself bore most heavily the unbelief and opposition of his own people. Their mission of carrying the gospel to the nations would meet fierce resistance from the Jews. Yet, he encouraged them to trust that if, in faith, they entrusted this work to God, the great obstacle, the fig tree nation, would be uprooted and cast into the sea (cf. 2 Chr. 7:20). In other words, Israel would be set adrift, no longer obstructing their God-given task.

Other passages carry a similar message: “The wicked shall be cut off from the land, and the treacherous shall be uprooted from it” (Prov. 2:22, perhaps the source of Jesus’ saying?). Likewise: “Every plant that my heavenly Father has not planted will be uprooted” (Mt. 15:13). Jude later described those corrupting the gospel through Judaistic influence as “trees without fruit, twice dead, uprooted,” followed immediately by the image of “raging waves of the sea, foaming out their own shame” (Jude 12–13)

The Unprofitable Servant

Through another parable, Jesus taught his disciples that in their service to him, success depends not only on faith but also on faithfulness.

In everyday life at that time, a servant returning from a long day of ploughing or tending sheep could not expect to immediately sit down and rest. His first responsibility was to prepare and serve his master’s meal. Only afterward would the servant take his own food, and all of this was done as a matter of duty, without thanks or special recognition. Though foreign to modern sensibilities, such a pattern was ordinary in that culture.

Jesus used this illustration to show the attitude required of his disciples. The servant working in the field represents the Jew laboring under the Law of Moses, the “curse on the ground” (Gen. 3:17–19) reflecting the burden of the Law (@dak), which brought knowledge of sin (Rom. 3:20). To “come into the house” symbolizes moving from the old covenant of works into the new covenant of grace. But entry into grace does not mean a life of ease. Just as the servant must still gird himself to serve his master personally, the disciple must take up the imitation of Christ, serving humbly and faithfully without pride or expectation of praise. True discipleship is not about personal merit, but about ordinary, ongoing duty before the Lord.

Paradoxically, it is through this very diligence and humility that faith is strengthened. Peter makes the same point, urging believers to “give all diligence” and add to their faith (2 Pet. 1:5). At best, a disciple must see himself as an “unprofitable servant” (Matt. 25:30) not because his service is worthless, but because all is owed to God already.

Finally comes the servant’s own meal. Though the food is provided by the master, the quality of it depends on how carefully the servant prepares it. Likewise, eternal life is a gift from God, yet the nature of our reward in Christ’s kingdom reflects the diligence and devotion with which we have served (1 Cor. 3:12–14; Luke 12:37).

The Lesson, Then and Now

The central principle of this parable is timeless and applies to every generation. No one in Christ should ever assume that the blessings available to them can be earned through personal effort alone. At best, after all is done, a person remains an ordinary servant, an “unprofitable servant”, for “in thy sight shall no man living be justified” (Ps. 143:2). No amount of good works can place God in anyone’s debt: “Who hath first given to him, and it shall be recompensed unto him again?” (Rom. 11:35).

(another reason the immortal soul doctrine is rejected)

True Christian service is expressed by Paul in reflecting on his work as a minister of Christ: “Though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me if I preach not the gospel! For if I do this thing willingly, I have a reward: but if against my will, I have a stewardship intrusted to me” (1 Cor. 9:16-17). In other words, faithful service must continue regardless of personal recognition or reward.

It is clear how this parable ties closely to the preceding teaching about the uprooting of the fig tree. Judaism, at that time, was the primary obstacle to the early preaching of the gospel, and only the preacher’s faith and God’s providence could overcome it. But why such fierce Jewish opposition to a movement so deeply rooted in their own tradition, the Hope of Israel? Because many were unwilling and still are, to abandon the notion of justification by works (Rom. 9:30-33; 10:3). Asking a Jew to see faithful adherence to the Law of Moses as “unprofitable” would have seemed outrageous. Even today, many earnest Gentile disciples struggle with the same misconception.

The challenge of divided loyalties, Moses or Christ? which confronted the early church is sharply illustrated in a parable that Luke includes at this point.

A brief geographical note adds context: “And it came to pass, as he went to Jerusalem, that he passed through the midst of Samaria and Galilee.” Luke is likely recording one of Jesus’ final circuits during the last months of his ministry, traveling through Samaria and returning to Galilee, though not staying long in any location. This northern journey is described as occurring “as he went to Jerusalem,” since that city was the ultimate destination of his pilgrimage.

Lepers, and a Leper

As Jesus and his companions approached a village, a group of ten lepers social outcasts, a “synagogue of misery” called out for his mercy.

Though marginalized and forced to keep their distance, they raised a united, repeated plea: “Jesus, Master, have mercy on us.” Even these pariahs had heard of Jesus’ healing power, and now their opportunity had come.

The narrative suggests that Jesus, engaged in conversation as he walked, did not notice them until their cry reached his ears. His response was immediate: “Go and show yourselves to the priests.” Though indirect, this was a promise of healing.

Without hesitation, they believed him and went. Along the way, they realized that their request had already been granted, their flesh was completely restored, clean, firm, and wholesome as a child’s. Excited and joyful, they hurried to the local Jewish priest to obtain official certification of their healing.

All except one. A Samaritan among them, recognizing his healing, did not follow Jesus’ instruction to show himself to the priest. Instead, prioritizing a higher duty, he ran back to Jesus. From a distance, his voice rang out in praise:

Psalm 30:8-12 (ESV)
8 To you, O Lord, I cry, and to the Lord I plead for mercy:
9 “What profit is there in my death, if I go down to the pit? Will the dust praise you? Will it tell of your faithfulness? @St. SteVen
10 Hear, O Lord, and be merciful to me! O Lord, be my helper!”
11 You have turned for me my mourning into dancing; you have loosed my sackcloth and clothed me with gladness,
12 that my soul may praise you and not be silent. O Lord my God, I will give thanks to you forever!

Unlike the others, he approached Jesus directly, pouring out ceaseless, fervent thanksgiving and prostrating himself at his feet.

“Were not ten cleansed? But where are the nine?” Jesus asked, with a hint of sadness: “Was no one found to return and give glory to God except this stranger?”

Then, addressing the man at his feet, He said: “Arise and go your way; your faith has saved you.” While faith in Christ had healed all ten, only this one reached the higher level of personal, ongoing dependence on him. The others, focused solely on outward observance, missed the deeper blessing. The Samaritan, through his faith and gratitude, was not just healed, he was saved.
