Historicalism teaches that most Biblical predictions would be fulfilled only some considerable time after they were given — fulfilled either once or repeatedly during the whole course of world history. Thus Historicalists regard the promised "seed" in the Protevangelium of Genesis 3:15 as referring not principally to that generation's Abel and Seth etc., but principally to Christ and His Christians (only to be born many centuries later).
Historicalists would agree with Preterists that there is indeed a very important sense in which Christ did come (invisibly) to Jerusalem, in punitive judgment, during A.D. 70. Yet historicists regard the various mentions of His coming inscripturated in Matthew chapter 24 and elsewhere, to refer to events throughout world history which all point principally toward His still-future visible coming on the clouds of heaven in power and great glory at the final judgment.
