If it doesn’t challenge you, it doesn’t change you. (Fred DeVito, physical trainer)

DeVito was probably thinking of people who want to get into better physical condition through exercise and training. But the principle can be applied to many other areas of life. Take education, for example. If learning comes easy, you may not pursue deeper concepts, because that would take some concerted effort. Are you up for a challenge today?

Physical training is good, but training for godliness is much better, promising benefits in this life and in the life to come. (1 Timothy 4:8)
