"In your struggle against sin, you have not yet resisted to the point of shedding your blood. 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 heart when he rebukes you, because the Lord disciplines those he loves, and punishes everyone he accepts as a son.'
Endure hardship as discipline; God is treating you as sons. For what son is not disciplined by his father? If you are not disciplined (and everyone undergoes discipline), then you are illegitimate children and not true sons.
Moreover, we have all had human fathers who discipline us and we respected them for it. How much more should we submit to the Father of our spirits and live! Our fathers disciplines us for a little while as they thought best; but God dsiciplines us for our good, that we may share in his holiness. No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it.
Therefore, strengthen your feeble arms and weak knees. 'Make level paths for your feet' so that the lame may not be disabled, but rather healed." (Heb 12:4-13)
