Whether it is running a marathon, playing a concerto on the piano, or writing a technical computer program, any significant challenge requires training. Effort can take you only so far. You must arrange your life around certain practices that will enable you to do what you cannot do now by willpower alone. It is no different when it comes to spiritual growth. Turning the other cheek, giving to those who ask, submitting to authority, being joyful in all circumstances, and not looking at another person lustfully is at least as demanding as running 26.2 miles. To accomplish these feats, we must train, and train wisely. We must engage in spiritual formation exercises (e.g., prayer, Scripture memorization, fasting, solitude, worship, etc.) for the purpose of receiving more of Christ’s life and power so that we can do what was before impossible.
