Idk what your point is here.
If
ALL that written was to be fulfilled in the desolation of Jerusalem what is left to be fulfilled?
Peter states the same thing that what was written was being fulfilled in his days:
Joel:
Acts 2:16 But this is
that which was spoken by the prophet Joel;
Acts 2:17 And it shall come to pass
in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:
Acts 2:20 The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord come:
That includes all he said from Joel including Acts 2:20 which is precisely the prophecy that Jesus used.
Acts 3:24 Yea, and
all the prophets from Samuel
and those that follow after, as many as have spoken, have likewise foretold of
these days.
Peter said he was living the "the last days", not last centuries, which all the prophets had spoken of.
The last days then became the last hour in the 1st century AD as John wrote his epistle:
1 Jo 2:18 Little youths,
it is the last hour; and even as ye heard that the antichrist doth come, even now antichrists have become many -- whence we know that it is the last hour;
