Hebrews 12:9-11
12:9 Besides, we have experienced discipline from our earthly fathers and we respected them; shall we not submit ourselves all the more to the Father of spirits and receive life?
12:10 For they disciplined us for a little while as seemed good to them, but he does so for our benefit, that we may share his holiness.
12:11 Now all discipline seems painful at the time, not joyful. But later it produces the fruit of peace and righteousness for those trained by it.
