text: in what book and chatpter of the bible does he say that know no man when the time is when the world ends? i really cant reamember and i would really like to know. you know when he says something like "knoweth no man or the angles of that year, day, hours..." something like that. luke 12:40 perhaps you are thinking of these?:  luke 12:40 "you also must be ready, because the son of man will come at an hour when you do not expect him."  luke 12:46 "the master of that servant will come on a day when he does not expect him and at an hour he is not aware of."
