1 Timothy 4:7-10

and the profane and old women's fables reject thou, and exercise thyself unto piety, for the bodily exercise is unto little profit, and the piety is to all things profitable, a promise having of the life that now is, and of that which is coming; stedfast [is] the word, and of all acceptation worthy; for for this we both labour and are reproached, because we hope on the living God, who is Saviour of all men — especially of those believing.
