And you have forgotten that word of encouragement that addresses you as sons: "My son, do not make light of the Lord's discipline, and do not lose heart1 when he rebukes you,
because the Lord disciplines those he loves,2 and he punishes everyone he accepts as a son."a37
Endure hardship as discipline; God is treating you as sons.4 For what son is not disciplined by his father?
If you are not disciplined (and everyone undergoes discipline),5 then you are illegitimate children and not true sons.
Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of our spirits6 and live!710
Our fathers disciplined us for a little while as they thought best; but God disciplines us for our good, that we may share in his holiness.811
No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace9 for those who have been trained by it.
Therefore, strengthen your feeble arms and weak knees.10
