The exercise unto godliness is a must

 If you point these things out to the brothers and sisters, you will be a good minister of Christ Jesus, nourished on the truths of the faith and of the good teaching that you have followed. 7 Have nothing to do with godless myths and old wives’ tales; rather, train yourself to be godly. 8 For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come. 9 This is a trustworthy saying that deserves full acceptance. 10 That is why we labor and strive, because we have put our hope in the living God, who is the Savior of all people, and especially of those who believe.
