There are several metaphors throughout the New Testament illustrating the nature of the Christian life and Christian community.  All the metaphors in 1 Timothy 4 are embedded with the need for training, for spiritual disciplines and practices which strengthen faith and promote spiritual health - Muscle training. If you dedicate yourself to these things, there will be no room for entertaining wacky stories which have no basis in truth. Instead, there will be lush spiritual growth, teachable spirits, humble service, supportive beliefs, compassionate ministry, and open fellowship.  The high values of the worthy servant of Christ need to be both used and guarded.  Just as your body  has physical muscles, so the Body of Christ has spiritual muscles. Faith is a muscle which needs to be stretched, exercised, rested, and supplied with plenty of protein and necessary nutrients. Let’s get to working out!
