What about those who don't eagerly wait for Him? Won't He appear a second time for them as well? Of course He will, but their experience of His second coming will be different from those who are eager to see Him. Think salvation vs. judgement. When I say Jesus also came circa 70AD, it is only valid in a very narrow sense that depends on accepting His first visitation (Daniel's 70th week) as being limited to the Jews [Matt 15:24]. Given the understanding that in a certain sense Jesus was first sent only to the Jews, and then later (after Stephen's martyrdom) was 'sent' to the Gentiles through the gospel by His Apostolic Church, we can apply the same pattern to see Jesus' coming in judgment was first against the world of Temple Judism (our past), with the anticipation He will come again later for salvation/judgment to the rest of the world (our future)[Rom 1:16, 2:9-19]. The broader point is that there is not a single universal frame of reference to describe Jesus' visitations. Think Einstein vs. Newton.
