We must subdue a hasty temper and control our words, and in this we shall gain great victories. Unless we control our words and temper, we are slaves to Satan. We are in subjection to him. He leads us captive. All jangling and unpleasant, impatient, fretful words are an offering presented to his satanic majesty. And it is a costly offering, more costly than any sacrifice we can make for God; for it destroys the peace and happiness of whole families, destroys health, and is eventually the cause of forfeiting an eternal life of happiness. — Adventist Home p. 437
