We are all accustomed to reading works on the spiritual disciplines of the Christian life. We know that as Christians we ought to discipline ourselves to ensure we maintain a lifelong focus on Word, prayer, and fellowship. And so we read the Bible and meditate on it, we pray as individuals and families, and we maintain fellowship with one another through local church worship and the sacraments or ordinances. Well and good! This is the stuff of the Christian life. Yet in his classic work Holy Helps for a Godly Life, Richard Rogers draws out a spiritual discipline that has largely been lost and neglected in recent years—the discipline of watchfulness.
