Thank you for the reminder. I agree. It is true that people could be called faultfinders when in fact they are confronting a brother biblically. It is also true that a person could be a faultfinder in the bad sense and justify himself that his is only holding Christians accountable to the Word of God.
Brothers, if someone is caught in a sin, you who are spiritual should restore him gently. But watch yourself, or you also may be tempted. (Gal. 6:1)
