Hebrews 12:7-17

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. Wherefore lift up the hands that hang down, and the palsied knees; and make straight paths for your feet, that that which is lame be not turned out of the way, but rather be healed. Follow after peace with all men, and the sanctification without which no man shall see the Lord: looking carefully lest there be any man that falleth short of the grace of God; lest any root of bitterness springing up trouble you, and thereby the many be defiled; lest there be any fornicator, or profane person, as Esau, who for one mess of meat sold his own birthright. For ye know that even when he afterward desired to inherit the blessing, he was rejected; for he found no place for a change of mind in his father, though he sought it diligently with tears.
