1 Timothy 4:6-8

If you keep these things before the minds of the brothers, you will be a good servant of Christ Jesus, trained in the words of the faith and of the right teaching which has been your guide: But have nothing to do with unclean and foolish stories. Give yourself training in religion: For the training of the body is of profit for a little, but religion is of profit in every way, giving hope for the life which now is, and for that which is to come.
