If another believer sins against you, go privately and point out the offense. If the other person listens and confesses it, you have won that person back.
Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother.
If another member of the church sins against you, go and point out the fault when the two of you are alone. If the member listens to you, you have regained that one.
When the Gentiles sin, they will be destroyed, even though they never had God’s written law. And the Jews, who do have God’s law, will be judged by that law when they fail to obey it.
