The purity of the church is every Christian’s concern. We all need to humbly and lovingly confront that which makes it impure when we become aware of it. Don’t just say, “Well, we’re praying for So–and–so that he’ll see the light.” That may not be enough. You’ve got the light—take it and shine it in his eyes! THE PROVOCATION OF DISCIPLINE Just cause for discipline occurs “if thy brother shall trespass [Gk., hamartanō, “to sin”] against thee” (v. 15). That is the basic New Testament word for sin.
