Hebrews 12:8

4 In your struggle against sin, you have not yet resisted to the point of shedding your blood.

5 And you have forgotten the exhortation that addresses you as sons: “My son, do not take lightly the discipline of the Lord, and do not lose heart when He rebukes you.

6 For the Lord disciplines the one He loves, and He chastises every son He receives.”

7 Endure suffering as discipline; God is treating you as sons. For what son is not disciplined by his father?

8 If you do not experience discipline like everyone else, then you are illegitimate children and not true sons.

9 Furthermore, we have all had earthly fathers who disciplined us, and we respected them. Should we not much more submit to the Father of our spirits and live?

10 Our fathers disciplined us for a short time as they thought best, but God disciplines us for our good, so that we may share in His holiness.

11 No discipline seems enjoyable at the time, but painful. Later on, however, it yields a harvest of righteousness and peace to those who have been trained by it.

12 Therefore strengthen your limp hands and weak knees.
