The sentence is correct. There is only one spelling mistake ('withhold' NOT withold). However, since it is not a complete sentence, you can add another information about either the father or the children: 'As long as we are obedient, your father does not withhold any good thing from us.' Or 'A father does not withhold any good things from us.'

no , is wrong . father hold you to this world . this is the best thing !
