Hebrews 12:11

For the moment all discipline seems painful rather than pleasant , but later it yields the peaceful fruit of righteousness to those who have been trained by it .

No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it.

Now no chastening for the present seemeth to be joyous, but grievous : nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised there by.
