Acts 24:15

Having hope toward God, which these also themselves look for, that there shall be a resurrection both of the just and the unjust.

Both this and the verse following are further elaborations of the truth that Christianity is not some wild and irresponsible new religion (though in another sense eternally new), but that its roots reach back to Eden and include all of the vital hopes which humanity ever had, such as the resurrection mentioned here. What was so clear to Paul was that Christianity is the fulfillment of Judaism, a fact to which the ancient leaders of Israel were totally blind.
