Hebrews 12:8-10

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.
