Hebrews 12:5-11
New King James Version (NKJV)

5 And you have forgotten the exhortation which speaks to you as to sons:

“My son, do not despise the chastening of the Lord,
Nor be discouraged when you are rebuked by Him;
6 For whom the Lord loves He chastens,
And scourges every son whom He receives.”

7 If you endure chastening, God deals with you as with sons; for what son is there whom a
father does not chasten?8 But if you are without chastening, of which all have become
partakers, then you are illegitimate and not sons.9 Furthermore, we have had human fathers who
corrected us, and we paid them respect. Shall we not much more
readily be in subjection to the Father of spirits and live? 10 For they indeed for a few
days chastened us as seemed best to them, but He
for our profit, that we may be partakers of His
holiness. 11 Now no chastening seems to be joyful for the present, but painful;
nevertheless, afterward it yields the peaceable fruit of righteousness to those who have been
trained by it.
