Happiness is a duty, quite as much a duty as truthfulness, honestly, or good temper. There are many Scripture words which exhort us to rejoice. Jesus was a rejoicing man. Although a “man of sorrows,” the deep undertone of His life, never once failing, was gladness. Joy is set down as one of the fruits of the Spirit, a fruit which should be found on every branch of the great Vine. St. Paul exhorted his friends to rejoice in the Lord. There are almost countless incitements to the gladness. We are to live a songful life. There are in the Scriptures many more calls to praise than to prayer.
