Hebrews 12:5-10

5And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him: 6For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. 7If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? 8But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons. 9Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live? 10For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness.
