5 and you have forgotten the exhortation that addresses you as to sons: “My son, do not regard lightly the Lord’s discipline, nor faint being reproved by Him.
6 For the Lord disciplines whom He loves, and He scourges every son whom He receives.
7 If you endure discipline, God is treating you as sons; for what son is there whom his father does not discipline?
8 But if you are without discipline, of which they have all become partakers, then you are illegitimate children and not sons.
