Summary of my sermon, based on Luke 17:1-10. Preached at Greenhills Christian Fellowship Toronto on Sunday, 14 June 2026.
In the Gospel of Luke, chapter 17, verses 1–10, Jesus delivers a series of teachings that address four core themes: the reality of sin, the necessity of forgiveness, the nature of faith, and the humble duty of the believer. These teachings, though appearing distinct, are bound together by the posture required of those who follow Christ.
The Inevitability and Severity of Sin
Jesus acknowledges the certainty of temptation in a fallen world, noting that temptations to sin are inevitable. However, he issues a grave warning regarding those who become the source of such temptation for others. The “little ones”—a term of endearment for the children of God—must be protected from stumbling. This warning applies to everyone, but it carries a particularly heavy weight for leaders, teachers, and preachers, who are called to adhere strictly to the Word of God to ensure they are not leading others astray.
The Command to Forgive
Because sin is an unavoidable reality, believers are given clear directives for handling it within the body of Christ. The primary response to a brother or sister who sins is to rebuke them—not out of malice, but with the goal of restoration and leading them back to repentance. When repentance is offered, the required response is complete forgiveness, regardless of how often the offense is repeated. This does not mean one should intentionally remain in vulnerable, abusive situations, but rather that the posture of the heart should be one of consistent, unlimited forgiveness.
The Nature of Faith
When faced with these difficult commands, the disciples asked Jesus to “increase our faith.” Jesus’s response highlights that the power of faith does not lie in its volume or magnitude, but in its existence and, most importantly, in the object upon which it is placed: Christ. Even a small amount of faith, when placed in the right person, enables the believer to accomplish the work of God. Ultimately, the greatest work of faith has already been accomplished through salvation from sin.
The Role of a Servant
Jesus concludes this teaching with an analogy regarding a servant’s duty. The point of this parable is not to portray God as a harsh taskmaster, but to define the proper mindset of a believer who has already received the grace of salvation. Just as a servant does not expect special thanks for simply fulfilling their assigned duties, the believer who has been saved by Christ is called to serve in humility, acknowledging that their obedience is a natural response to being redeemed.
Ultimately, the call to serve one another—by protecting each other from sin, rebuking in love, and forgiving freely—mirrors the humility displayed by Christ in his own life and death on the cross.
