Notice a couple of things in this text:
Rev1:1
The Revelation of Jesus Christ, which God gave unto him [/unto Jesus],
to shew unto his servants things which must come to pass IN QUICKNESS; and he sent and signified
it by his angel
unto his servant John:
Rev1:2
Who
bare record of the word of God, and of the testimony of Jesus Christ, and of all things that he saw.
Rev1:3
Blessed
is he that
readeth, and they that
hear the words of this prophecy, and
keep[/guard] those things which are written therein: for the time
is at hand.

Verse 1 says (in the Greek), "things which must come to pass IN
QUICKNESS [G1722
G5034 (preposition,
NOUN)]"...
...whereas "shortLY" (as you have it ^ is an
ADVERB instead);
this phrase is talking about the aspect that goes with "
TO SHOW UNTO His servants..." (which aspect doesn't start
until after the first three chapters) corresponding with where
v.4:1 states, "
AFTER THESE things... 'come up here and
I WILL SHOW YOU what things must...'" (that is the first mention of
"SHOW," besides 1:1's introduction saying so);
THAT's the part "which must come to pass IN QUICKNESS" (i.e. within a relatively brief amount of time, once it starts [
aka the Tribulation Period - 7 yrs duration - So, "the SEALS"/"beginning of birth PANGS" are part of what John is
"SHOWn" starting in v.4:1 and thus are a part of the "things which must come to pass IN QUICKNESS" (i.e. the "far-future" aspects of the Book)])
--
Verse 3 indeed is talking about what John "
bare RECORD of" (i.e. the contents of the entire Book of Rev), which means that: [Blessed is he that...]
"readeth" and
"hear" and
"keep/guard" is what pertains to ITS [v.3's] OWN wording of: "
for the time is at hand" (i.e. including the 7 letters in chpts 2-3 that indeed went to the churches ["what the Spirit saith unto the churchES"]
STARTING IN THE FIRST CENTURY ); Verse 3's "for the time is at hand" is not reaching back to refer to the "TO SHOW UNTO" (corresponding with 4:1's "and I WILL SHOW YOU..." part, which part only started when John was told to "come up here and I will..." [John's change of location, from that point]);
--this means that 1:1's "TO SHOW UNTO His servants things which must come to pass IN QUICKNESS" correlates with 1:19c / 4:1 (the "[far-]future" aspects of the Book, i.e. the Trib yrs [7yrs]), not to mention, with 7:3;
Whereas "the things WHICH ARE" (chpts 2-3; 1:19b) are NOT said (of THEM) that THEY are "things which must come to pass in quickness," BY CONTRAST ... and nowhere does it say that John is "SHOWn" this aspect [though yes, he "saw" things], it just says [or gives the instruction,] "WRITE";
--under v.1 see the Greek wording "G1722 G5034" (as pointed out at the top) - https://www.blueletterbible.org/kjv/rev/1/1/t_concif_1168001 (where "G1722 en " is not translated into the English... and where G5034 is a noun not the adverb "shortLY")
I agree that "the beginning of birth PANGS" exactly match the "SEALS" of Rev6 (because they ARE the same thing); Luke 21:12 informs us that these take place AFTER the "70ad events" of vv.12-24a,b (with pt c following on from those); but note, the "70ad events" spelled out in that section, which come "BEFORE ALL these [BEFORE ALL these beginning of birth pangs]" don't take place "immediately before" the BoBPs (the "unfolding" of ASPECTS OF v.24's items do, though!) IOW, the SEALS are included WITHIN the "7 year Tribulation Period" (so that, the "SEALS - TRUMPETS - VIALS" all take place WITHIN those "future" 7 years leading up to Christ's Second Coming to the earth Rev19 [but FOLLOWING "our Rapture [IN THE AIR]");
--ONE set of "SEE-then-FLEE" fits in the 70ad events ("
BEFORE" the BoBPs), per Lk21:12,23,20;
--THE OTHER set of "SEE-then-FLEE" fits in the far-future TRIB yrs (
AFTER the BoBPs, in Matt24!)
They are distinct, and
have completely distinct [OPPOSITE] outcomes / ends (the former leads to "they shall be led away captive INTO ALL THE NATIONS"; the latter shows them being gathered "FROM THE FOUR WINDS" where they'd been judicially scattered, gathered "one by one" INTO ONE PLACE UPON THE EARTH...
...because Matt24:29-31 corresponds with Isaiah 27:9,12-13 [and Isa27:
9 corresponds with both Rom11:
27 [re: Israel's "FUTURE"] and parts of Dan9:24...with its TIME-PROPHECY regarding "thy [Daniel's] people," and "thy [Daniel's] holy city [/Jerusalem--see Isa27:9,12-13's destination-location]"... at the time of the
"GREAT" trumpet [also mentioned in Matt24:29-31... which is AFTER the tribulation... and is NOT a "RAPTURE / SNATCH"].)
