The problem I see for most eschatologies is a failure to believe the various time statements in the new testament.
(Acts 2:17 'And in the last days it will be,' God says, 'that I will pour out my Spirit on all people, and your sons and your daughters will prophesy, and your young men will see visions, and your old men will dream dreams.)
(Acts 3:24 And all the prophets, from Samuel and those who followed him, have spoken about and announced these days.)
(Acts 3:25 You are the sons of the prophets and of the covenant that God made with your ancestors, saying to Abraham, 'And in your descendants all the nations of the earth will be blessed.')
We have in the above Peter stating they are in the "last days", and that all the prophets from Samuel "announced these days "
We have Paul stating that the goals of the ages were upon them:
1 Cor 10:11 These things happened to them as examples and were written for our instruction, on whom the ends of the ages have come)
end = telos from a primary tello (to set out for a definite point or goal)
John writes in his letter at the end of Peter's "last days" that they were in the "last hour" of the days that were "announced " by all the prophets from Samuel and those that followed him.
(1 John 2:18 Children, it is the last hour, and just as you heard that the antichrist is coming, so now many antichrists have appeared. We know from this that it is the last hour.)
