1 Timothy 4:7-10

But avoid foolish and old wives' fables: and exercise thyself unto godliness. For bodily exercise is profitable to little: but godliness is profitable to all things, having promise of the life that now is, and of that which is to come. A faithful saying and worthy of all acceptation. For therefore we labor and are reviled, because we hope in the living God, who is the Saviour of all men, especially of the faithful.
