I am the resurrection and the life (Egō eimi hē anastasis kai hē zōē). This reply is startling enough. They are not mere doctrines about future events, but present realities in Jesus himself. “The Resurrection is one manifestation of the Life: it is involved in the Life” (Westcott). Note the article with both anastasis and zōē. Jesus had taught the future resurrection often (Joh 6:39), but here he means more, even that Lazarus is now alive.
Though he die (kan apothanēi). “Even if he die,” condition (concession) of third class with kai ean (kan) and the second aorist active subjunctive of apothnēskō (physical death, he means).
Yet shall he live (zēsetai). Future middle of zaō (spiritual life, of course).
