1 Timothy 4:7-10

Avoid profane and silly myths. Train yourself for devotion, for, while physical training is of limited value, devotion is valuable in every respect, since it holds a promise of life both for the present and for the future. This saying is trustworthy and deserves full acceptance. For this we toil and struggle, because we have set our hope on the living God, who is the savior of all, especially of those who believe.
