To whom does the Lord reveal secrets? The Bible says His deep truths-His secrets-are for those who revere and worship Him. Rare people who learn from their Teacher to redirect focus off self and onto God show a life of peace and inner joy-despite life's challenges. Hannah Whitall Smith, a Quaker woman from Pennsylvania, first penned "The Christian's Secret of a Happy Life" in 1870. In this classic work, she both defined a life of joyous fruitfulness, and the obstacles to that path. Her words reflect so many passages of Scripture that we have included those biblical references in the text of her book, and provided a Bible study workbook for her work. You might ask an older couple on their 50th anniversary about the secret of their lasting marriage. Hannah Whitall Smith calls us to ask her the secret of her happy life as a Christian. She reveals the secret so that we, too, need not be "unfruitful in the true knowledge or our Lord Jesus Christ" but may have "entrance into His eternal kingdom abundantly supplied" to us.
