5 And have you forgotten the exhortation which addresses you as sons?-- "My son, do not regard lightly the discipline of the Lord, nor lose courage when you are punished by him.
6 For the Lord disciplines him whom he loves, and chastises every son whom he receives."
7 It is for discipline that you have to endure. God is treating you as sons; for what son is there whom his father does not discipline?
8 If you are left without discipline, in which all have participated, then you are illegitimate children and not sons.
9 Besides this, we have had earthly fathers to discipline us and we respected them. Shall we not much more be subject to the Father of spirits and live?
