1 Timothy 4:6-8

If thou put the brethren in mind of these things, thou shalt be a good minister of Christ Jesus, nourished in the words of the faith, and of the good doctrine which thou hast followed until now: but refuse profane and old wives’ fables. And exercise thyself unto godliness: for bodily exercise is profitable for a little; but godliness is profitable for all things, having promise of the life which now is, and of that which is to come.
