Hebrews 12:8

But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons.

But if you are without discipline, of which all have been made partakers, then are you illegitimate, and not children.

But if ye are without chastening, whereof all have been made partakers, then are ye bastards, and not sons.

and if ye are apart from chastening, of which all have become partakers, then bastards are ye, and not sons.

If you do not experience discipline like everyone else, then you are illegitimate children and not true sons.
