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.
