16 If he won't listen, take one or two others along so that the presence of witnesses will keep things honest, and try again. 17 If he still won't listen, tell the church. If he won't listen to the church, you'll have to start over from scratch, confront him with the need for repentance, and offer again God's forgiving love.
Matthew Henry's Commentary on Matthew 18:16-17
Commentary on Matthew 18:15-20
(Read Matthew 18:15-20)
If a professed Christian is wronged by another, he ought not to complain of it to others, as is often done merely upon report, but to go to the offender privately, state the matter kindly, and show him his conduct. This would generally have all the desired effect with a true Christian, and the parties would be reconciled. The principles of these rules may be practised every where, and under all circumstances, though they are too much neglected by all. But how few try the method which Christ has expressly enjoined to all his disciples! In all our proceedings we should seek direction in prayer; we cannot too highly prize the promises of God. Wherever and whenever we meet in the name of Christ, we should consider him as present in the midst of us.
