Without getting into allot of detail did Christ die for You? If yes, have your ethics changed to glorify God? If yes again, are they affecting "all" you come in contact with. If yes, then Christ died for "all" in a general way. We could ask further if the Gospel is heard by both the elect and non-elect, if yes, then Christ died for all at least in a general way, etc. When Christ died/rose again He secured the ONLY way of salvation. Thus, the non-elect have no other way to God--thus, Christ died for all, etc.
