The "must" in Revelation 22:6, 1:1 means that the
prophecies of Revelation chapters 6-22 aren't
conditional or changeable, but will be fulfilled
exactly as they've been foretold.

The Olivet Discourse (Matthew 24) isn't about the
events leading up to and including the destruction
of Jerusalem and the temple in 70 AD, because the
abomination of desolation (Matthew 24:15, Daniel
11:31,36, 2 Thessalonians 2:4) didn't happen in 70
AD, neither did the second coming of Jesus Christ
and the gathering together (rapture) of the church
to him (Matthew 24:30-31, 2 Thessalonians 2:1,
1 Thessalonians 4:15-17).

No evidence requires an early date for Revelation.
Irenaeus' famous quote in "Against Heresies" clearly
refers to the apostle John seeing the vision of the
book of Revelation in the 90s AD.
---
Nothing requires that Revelation chapters 6-22
had to concern events dealing directly with the
circumstances of their original first-century
recipients. Only the events of the letters of
Revelation chapters 2-3 dealt directly with the
circumstances of seven first-century local church
congregations in the Roman province of "Asia"
(Revelation 1:11).
The myriad and quite detailed events of Revelation
chapters 6-22 didn't happen in the first century,
or even the second. They've never been fulfilled,
just as the prophesied events of Matthew 24, which
are a short summary of the events of Revelation
chapters 6-19, have never been fulfilled.

The temporary darkening of the sun and reddening of
the moon at one point during the first stage of the
coming tribulation (Revelation 6:12) isn't the same
event as the temporary darkening of both the sun and
the moon at the second coming after the entire
tribulation (Matthew 24:29-31) of Revelation chapters
6-18 is over.
Matthew 24 doesn't mention the detailed events of
Revelation chapters 8-22, such as the coming
tribulation's trumpets, beasts, bowls (or vials), or
the coming millennium, new heaven, new earth, and new
Jerusalem, because Matthew 24 is just a short summary
of the coming tribulation and second coming; Jesus
knew at that time that the apostles weren't ready yet
to get all the many details of things to come (John
16:12-13).
Matthew 24 does mention the still-unfulfilled
abomination of desolation spoken of by Daniel the
prophet (Matthew 24:15), when the still-unfulfilled
Antichrist will attack a third Jewish temple in Jerusalem,
stop the Mosaic sacrifices in front of it, and then sit in
the temple and proclaim himself God (Daniel 11:31,36,
2 Thessalonians 2:4), thus beginning his 42-month
Luciferian reign of terror over the earth, the awful
details of which are given in Revelation 13:4-18.
And Matthew 24 does mention the still-unfulfilled
second coming of Jesus Christ (Matthew 24:30-31),
when, after the entire tribulation (Matthew 24:29)
of Revelation chapters 6-18 is over, he will return
and marry the church and destroy the Antichrist
(Revelation 19:7-21).
Before the second coming, Revelation shows clearly
that the church will have to go through the reign of
the Antichrist and his worldwide persecution of the
church (Revelation 13:7-10, 14:12-13, 20:4, Matthew
24:9-13).
2 Thessalonians 2 shows clearly that Jesus can't
come to gather together the church until sometime
after the Antichrist commits the abomination of
desolation (2 Thessalonians 2:1-4), for when Jesus
comes to gather together the church he will destroy
the Antichrist (2 Thessalonians 2:1,8).
The scriptures couldn't have made it any easier for
us to understand what we're going to have to face.
Jesus has told us everything beforehand in the
Olivet Discourse (Mark 13:23) and in the book of
Revelation (Revelation 1:1, 22:16). We'll have only
ourselves to blame if we're surprised by anything
that's going to happen, or surprised that we'll have
to go through anything that's going to happen.
If Jesus cared enough about the end times to tell us
everything in such great detail, how could we possibly
feel no need to study what he said? Is not our job to
study to show ourselves approved unto God (2 Timothy
2:15), to know all of the scriptures (2 Timothy
3:15-17), and live by their every word (Matthew 4:4)?
Isn't it a good practice to preach the word of God
(2 Timothy 4:2), even every single thing that Jesus
said? (Matthew 28:19-20). How then can we ignore and
avoid Jesus' words in the Olivet Discourse and
Revelation, as if they're irrelevant?
The good news, or gospel, of Jesus Christ includes
everything in the books of the Bible called the
Gospels (Mark 1:1). So we can't preach the good news
without including the Olivet Discourse. We can't even
leave out the smallest detail anywhere in the Gospels
(Matthew 26:13) or any other part of the Bible. Every
word is to be lived by (Matthew 4:4), every part is
profitable for doctrine, for reproof, for correction,
for instruction in righteousness, that the man of God
may be perfect, throughly furnished unto all good
works (2 Timothy 3:16-17).

Our best interest is to be reading in every section
of the Bible at the same time. We shouldn't spend too
long in just one section and avoid the others until
some future time. We can think of the Bible as
seven volumes:
1. Genesis to Deuteronomy (Pentateuch)
2. Joshua to Esther (History)
3. Job to Song of Songs (Poetry)
4. Isaiah to Malachi (Prophets)
5. Matthew to Acts (Gospels & Acts)
6. Romans to Hebrews (Paul, & Silas?)
7. James to Revelation (Other Apostles)
We can read at least one chapter in each volume
every day, so that we're always current in each
volume. When we reach the end of a volume, we can
simply start again at the first chapter of that
volume, and not wait until we've finished all of the
other volumes, for the larger volumes are less dense
with doctrine, whereas the shorter volumes are packed
dense with doctrine, so that a more frequent reading
of the smaller volumes is in order.
What a feast our God has laid before us in his word!
We can keep the feast every day, a seven-course
banquet packed full of life-giving power (Matthew 4:4).
And as we stay current in each volume of the Bible,
we'll see all the myriad and amazing connections
between them. We'll see how they all complement each
other, explain each other, support each other, like a
finely woven tapestry where every thread is important,
where no thread can be pulled on in an attempt to
toss it away, without affecting many other threads,
indeed the entire tapestry, so that it will unravel
into a meaningless rag should we dare to try to excise
the knowledge of any of it as "not in our best
interest".
