The Beauty of Self Control is a helpful devotional by J. R. Miller. Miller excels as a writer on of Christian life.

"A temper under control, a voice cheerful with hope, and a countenance bright with kindness are Invaluable possessions to any man or woman." Perfect self-control," he says, "is ideal life. A man is kingly when he has complete mastery of his temper, his feelings, his appetites; when he can be quiet under injury and wrong; when he can stand amid temptations and not yield to them. Not only is self-control strong, it is also beautiful. Anger is not beautiful. Ungoverned temper is not lovely. Rage is demonic. But a spirit calm, strong, and unflustered, amid storms of feeling and all manner of disturbing emotions, is sublime in Its beauty."

Miller authored nearly 100 books and articles.
