'Discipline' in the Bible

and you have quite forgotten the encouraging words which are addressed to you as sons, and which say, "My son, do not think lightly of the Lord's discipline, and do not faint when He corrects you;

The sufferings that you are enduring are for your discipline. God is dealing with you as sons; for what son is there whom his father does not discipline?

And if you are left without discipline, of which every true son has had a share, that shows that you are bastards, and not true sons.

Besides this, our earthly fathers used to discipline us and we treated them with respect, and shall we not be still more submissive to the Father of our spirits, and live?

Now, at the time, discipline seems to be a matter not for joy, but for grief; yet it afterwards yields to those who have passed through its training a result full of peace--namely, righteousness.
