But those 7 churches are typical of churches everywhere at all times. They are not "church ages" unless solid scriptural evidence proves otherwise.
The whole book of Revelation is PROPHECY through to the second coming of Christ. The letters to the seven "churches" are the "fullness of the Gentiles coming into spiritual Israel." Then Daniel 9:26 is fulfilled.
Romans 11:
25 For I do not desire, brethren, that you should be ignorant of this mystery, lest you should be wise in your own opinion, that blindness in part has happened to Israel until the
fullness of the Gentiles has come in. 26 And so all Israel will be saved, as it is written:
“The Deliverer will come out of Zion,
And He will turn away ungodliness from Jacob;
27 For this
is My covenant with them,
When I take away their sins.”
Daniel 9:24-27
the matter, and understand the vision:
24 “Seventy weeks are determined
For your people and for your holy city,
To finish the transgression,
To make an end of sins,
To make reconciliation for iniquity,
To bring in everlasting righteousness,
To seal up vision and prophecy,
And to anoint the Most Holy.
25 “Know therefore and understand,
That from the going forth of the command
To restore and build Jerusalem
Until Messiah the Prince,
There shall be seven weeks and sixty-two weeks;
The street shall be built again, and the wall,
Even in troublesome times.
26 “And after the sixty-two weeks
Messiah shall be cut off, but not for Himself;
And the people of the prince who is to come
Shall destroy the city and the sanctuary.
The end of it
shall be with a flood,
And till the end of the war desolations are determined.
27 Then he shall confirm a covenant with many for one week;
But in the middle of the week
He shall bring an end to sacrifice and offering.
And on the wing of abominations shall be one who makes desolate,
Even until the consummation, which is determined,
Is poured out on the desolate.”
Unfortunately, your preterist eschatological beliefs won't let you "see" this and you won't be able to see the 3-fold prophecy that these are also specific church ages (in order), but for anyone else, I post this.
