For consider Him who endured such hostility from sinners against Himself, so that you will not grow weary and lose heart. In your struggle against sin you have not yet resisted to the point of shedding your blood. And have you completely forgotten this word of encouragement that addresses you as a father addresses his child?
“My son, do not despise the discipline of the Lord,
Nor be discouraged when you are rebuked by Him;
For whom the Lord loves He disciplines,
And chastens every child whom He receives.”
Endure hardship as discipline; God is treating you as His children. For what children are not disciplined by their father? If you are not disciplined ~ and everyone undergoes discipline ~ then you are not legitimate, not true sons and daughters at all. 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 spirits and live! They disciplined us for a little while as they thought best; but God disciplines us for our good, in order 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 the hands which hang down, and the weak knees, and make straight paths for your feet, so that the limb which is impaired may not be dislocated, but rather be healed. Pursue peace with all people, and the holiness without which no one will see the Lord. See to it that no one fails to obtain the grace of God; that no root of bitterness springing up causes trouble, and by it many become defiled…
~ Hebrews 12:3-15
