Matthew 18:15

Moreover. Jesus here begins a new section of instruction, but one that is closely related in thought to that which precedes it, particularly to vs. 12-14. In the parable of the Lost Sheep, Jesus stresses the profound concern the Father feels for “one of these little ones” (v. 14) “which is gone astray” (see on v. 12). Now He proceeds to discuss (vs. 15-20) what attitude a Christian should take toward a fellow believer who has injured him.

Shall trespass. Gr. hamartano, literally, “to miss the mark”; hence, “to err,” “to do wrong,” or “to sin.” The “brother” who “errs” is evidently the same as the “one sheep” that “went astray” (see on v. 12).

Go and tell him. See on Lev. 19:17, 18. Compare Gal. 6:1. This is more than a wise admonition; it is a command. “For evils that we might have checked, we are just as responsible as if we were guilty of the acts ourselves” (DA 441).

Thee and him alone. To circulate reports concerning what “thy brother” may have done will make it more difficult, perhaps even impossible, to reach him. Here, perhaps more than in any other aspect of personal relationships, it is our privilege to apply the Golden Rule (see on ch. 7:12). The less publicity that is given to a wrong act, the better.

Gained thy brother. Someone has said that the best way to dispose of our enemies is to make friends of them. The talent of influence is a sacred trust, one for which we will inevitably be called upon to give account in the day of judgment. “Blessed are the peacemakers: for they shall be called the children of God” (see on ch. 5:9).
