Hebrews 12:7-11
12:7 Endure your suffering as discipline; God is treating you as sons. For what son is there that a father does not discipline?
12:8 But if you do not experience discipline, something all sons have shared in, then you are illegitimate and are not sons.
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.
