 Paul goes on to say, 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 everybody undergoes discipline, then you're illegitimate children and not true sons. Now, that almost sounds contradictory. How can you be not disciplined if everyone undergoes discipline? I think it's a matter of how you take it. You can receive discipline and say, well, it was just bad luck.
