Hebrews 12:6-11

For whom the Lord loveth he chasteneth, And scourgeth every son whom he receiveth. It is for chastening that ye endure; God dealeth with you as with sons; for what son is there whom his father chasteneth not? But if ye are without chastening, whereof all have been made partakers, then are ye bastards, and not sons. Furthermore, we had the fathers of our flesh to chasten us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live? For they indeed for a few days chastened us as seemed good to them; but he for our profit, that we may be partakers of his holiness. All chastening seemeth for the present to be not joyous but grievous; yet afterward it yieldeth peaceable fruit unto them that have been exercised thereby, even the fruit of righteousness.
