Anger

"Be ye angry and sin not." The life of our Savior, as well as the precepts of the apostles, clearly teaches us, that there may be occasions, on which we may have feelings of displeasure, and even of anger, without sin. Sin does not necessarily attach to anger, considered in its nature, but in its degree. Nevertheless, anger seldom exists in fact, without becoming in its measurement inordinate and excessive. Hence it is important to watch against it, lest we be led into transgression. Make it a rule therefore, never to give any outward expressions to angry feelings, (a course which will operate as a powerful check upon their excessive action,) until you have made them the subject of reflection and prayer. And thus you may hope to be kept.
