For to what angel did God ever say, Thou art my son; this day have I become thy Father? and again, I will be a father to him, and he shall be to me a son?

and have you forgotten the exhortation which reasons with you as sons? My son, do not despise the training of the Lord, Nor faint when he corrects you;

It is for discipline that you are enduring these sufferings. God is dealing with you as sons. For what son is there whom his father does not discipline?
