The Battle for Self-control in Speech
God requires parents, by self-control, by an example of solid character building, to disseminate light within the immediate circle of their own little flock. No trifling, common conversation is to be indulged. God looks into every secret thing of life. By some a constant battle is maintained for self-control. Daily they strive silently and prayerfully against harshness of speech and temper. These strivings may never be appreciated by human beings. They may get no praise from human lips for keeping back the hasty words which sought for utterance. The world will never see these conquests, and if it could, it would only despise the conquerors. But in heaven's record they are registered as overcomers. There is One who witnesses every secret combat and every silent victory, and He says, “He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city.” If you refuse to storm or fret or scold, the Lord will show you the way through. He will help you to use the talent of speech in such a Christlike way that the precious attributes of patience, comfort, and love will be brought into the home.
