Hebrews 12:4-8

You have not yet resisted to the point of shedding blood in your striving against sin; and you have forgotten the exhortation which is addressed to you as sons, “MY SON, DO NOT REGARD LIGHTLY THE DISCIPLINE OF THE LORD, NOR FAINT WHEN YOU ARE REPROVED BY HIM; FOR THOSE WHOM THE LORD LOVES HE DISCIPLINES, AND HE SCOURGES EVERY SON WHOM HE RECEIVES.” It is for discipline that you endure; God deals with you as with sons; for what son is there whom his father does not discipline? But if you are without discipline, of which all have become partakers, then you are illegitimate children and not sons.
