Monday, January 7 Be wrathful, but do not sin.—Eph. 4:26. Few people have been treated as badly as David was. Still, that friend of God did not allow resentment to gnaw away at him. Rather, he wrote: “Let go of anger and abandon rage; do not become upset and turn to doing evil.” (Ps. 37:8) The most important reason to “let go” of anger is to imitate Jehovah, who “has not dealt with us according to our sins.” (Ps. 103:10) But there are also practical benefits to ‘letting go’ of anger. Anger can cause such physical problems as high blood pressure and respiratory trouble. It can affect the liver and the pancreas, and it can cause digestive problems. When we are angry, we do not always think clearly. And at times a fit of anger may be followed by a prolonged period of depression. On the other hand, “a calm heart gives life to the body,” says the Bible. (Prov. 14:30) How, then, can we deal with hurt feelings and gain our brother? We can do so successfully by applying the Bible’s wise advice. w18.01 10 ¶14-15
