Believers will be raised on the Last Day. Jesus makes a simple statement. He doesn't come up with some complicated scheme for the last days but simply assures the believer that he will be raised at the Last Day. The early creeds of the church simply looked forward to the end of the world and the resurrection of the dead at Christ's coming. He will come again but it will not be until the Last Day. History has to play itself out according to God's Plan and then the end will come.
