Hebrews 12:11
No discipline seems enjoyable at the time, but painful. Later on, however, it yields a harvest of righteousness and peace to those who have been trained by it.
Berean Standard Bible
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 thereby.
All chastening seems for the present to be not joyous but grievous; yet afterward it yields the peaceful fruit of righteousness to those who have been trained by it.
