'Discipline' in the Bible

You have forgotten the encouragement that is addressed to you as sons: "My son, do not think lightly of the Lord's discipline or give up when you are corrected by him.

What you endure disciplines you: God is treating you as sons. Is there a son whom his father does not discipline?

Now if you are without any discipline, in which all sons share, then you are illegitimate and not God's sons.

No discipline seems pleasant at the time, but painful. Later on, however, for those who have been trained by it, it produces a harvest of righteousness and peace.
