For bodily exercise has some value, but godliness has value for all things, having the promise of the life which is now, and of that which is to come.

 4:11-16 Make it your business to hand on and to teach these commandments. Do not give anyone a chance to despise you because you are young; but in your words and in your conduct, in love, in loyalty and in purity, show yourself an example of what believing people should be. Until I come, devote your attention to the public reading of the scriptures, to exhortation and to teaching. Do not neglect the special gift which was given to you, when the voices of the prophets picked you out for the charge which has been given to you, when the body of the elders laid their hands upon you. Think about these things; find your whole life in them, that your progress may be evident to all. Take heed to yourself and to your teaching; stick to them; for if you do, you will save yourself and those who hear you.
