In Luke 17:1-10, Jesus teaches on three topics related to Christian discipleship. These texts should be read in context of the Gospel, which gives weight and motivation for Christians to obey.
While temptations to sin are sure to come, we should never entice others to sin. We should pay attention to how our conduct may be leading others into sin (vs 1-4). While it may be difficult, Christians should rebuke their brother or sister when they sin, and forgive them as many times as they repent. As God through Christ forgave us, we should forgive others.
To genuinely forgive others, we need faith in the person (Messiah, God incarnate) and work (atoning sacrifice for sin) of Jesus Christ. Jesus is both author and perfector of our faith, so seek him in times of spiritual weakness. Remember, God can do the seemingly impossible through small, yet genuine, faith (vs 5-6).
Lastly, Jesus makes clear that no matter how well we serve God, he is never indebted to us as we are simply doing our duty (vs 7-10). Continue to serve faithfully and humbly, remembering that God gives us the victory through Jesus Christ our Lord; our service is in response to his grace, not a cause for merits. With the gospel of Jesus Christ as our foundation, let’s be people who fight sin/causes of sin, forgive others, trust in God for faith, and serve humbly.
