1 Timothy 4:7-10

But keep away from those godless legends, which are not worth telling. Keep yourself in training for a godly life. Physical exercise has some value, but spiritual exercise is valuable in every way, because it promises life both for the present and for the future. This is a true saying, to be completely accepted and believed. We struggle and work hard, because we have placed our hope in the living God, who is the Savior of all and especially of those who believe.
