God has given you life and all the rich blessings that make it enjoyable, and in return He has claims upon you for service, for gratitude, for love, for obedience to His law.... He requires you to control passion, to restrain selfish thoughts and actions, and to leave fretful words unspoken. Would Jesus require this self-control, if it were not for your real happiness to practice it? No; He wishes you to cultivate such traits of character as will bring peace to your own hearts, and enable you to brighten other hearts and lives with the sunshine of love, joy, and cheerful contentment.
