1 Timothy 4:7–8
7 Have nothing to do with lirreverent, silly mmyths. Rather ntrain yourself for godliness; 8 for while bodily training is of some value, ogodliness is of value in every way, pas it holds promise for the present life and also for the life to come.
Hebrews 12:11
11 For the moment all discipline seems painful rather than pleasant, but later it yields the mpeaceful fruit of righteousness to those who have been ntrained by it.
