I guess it depends on the meaning of "ALL" ;-) -- "As in Adam all die, so in Christ all will be made alive." As far as physical death is concerned (the context of 1 Cor 15), not "all" people have died (e.g., Enoch: Gen 5:24; cf. Heb 11:5, Elijah: 2 Kings 2:11). Likewise, "all" will not be made spiritually alive by Christ, because some will choose to suffer eternal spiritual death in hell.
You don't put new wine in old wineskins - everybody knows that! ;-)
