Read Luke 17 today.

One of the things we find in this chapter is a teaching relative to confronting someone who has sinned. This is one of the challenging things for us because, in our culture today, we do not want to get involved in the lives of other people. Yet, as Jesus was talking to His disciples, He did not give them the option of ‘not getting involved.’
As Jesus addressed this subject, He avoided both extremes of it. He did not give the option of ignoring the sin of another person because He said to rebuke them. If you rebuke someone else, you are involved. Nor did He offer the option of merely issuing condemnation of the person. The word rebuke may sound harsh to us, but we need to read on. The rebuke described by Jesus comes with an attitude seeking forgiveness and reconciliation rather than condemnation. Confronting the sin of another person is for the purpose of lifting them up, rather than tearing them down.
How do you think our world would be different if we adopted that approach in our relationships with other people?
Luke 17:1-4 NLT
One day Jesus said to his disciples, “There will always be temptations to sin, but what sorrow awaits the person who does the tempting! [2] It would be better to be thrown into the sea with a millstone hung around your neck than to cause one of these little ones to fall into sin. [3] So watch yourselves! “If another believer sins, rebuke that person; then if there is repentance, forgive. [4] Even if that person wrongs you seven times a day and each time turns again and asks forgiveness, you must forgive.”
