“Exercise thyself unto piety [or godliness]; for bodily exercise is profitable for a little, but piety [godliness] is profitable for everything, having promise of life of the present one and of that to come” (1 Timothy 4:8). People nowadays are most conscious of the need to engage in physical exercise, but unfortunately God’s people are considerably negligent regarding the need for spiritual exercise. They may have had some experience of being in the school of Christ where they learn something of God’s truth mentally, yet they are quite ignorant when it comes to the gymnasium of Christ where through spiritual exercise they may learn of Christ himself and grow up in Him daily. This causes them to be large in head but small in feet. They know a lot but advance very little along the pathway towards spiritual maturity.
