You have sourced the seven year time span from an interpretation of the book of Daniel.
I know I've stated this before, but I'll say it again here:
[a few brief points, coz I don't have a lot of time for typing right now]
--Rev1:
1 / 1:19
c / 4:
1 = "[TO
SHEW unto..] ...things which
must come to pass
IN QUICKNESS [NOUN]" (not "soon [adverb]");
--"the beginning of birth PANGS"
= "the SEALS [1-5 at least]"... and Lk21:
12 states that the 70ad events (in vv.12-24a,b) must take place
"BEFORE ALL THESE" beginning of birth pangs that vv.8-11 just listed (this is the "SEQUENCE" issues in the Olivet Discourse that many miss); this AGREES with the SEQUENCE also between Matt22:7 [70ad events] and 22:8 ["THEN SAITH HE to his servants..." AFTER the 70ad events... i.e. in the 95ad writing of Rev...
1:1 / 7:3 (the "144,000
servants of our God"--these have not yet existed on the earth, in their role shown in Rev);
--when viewing the "IN QUICKNESS [NOUN]" time-period (that 1:1 / 1:19c / 4:1 is speaking of), noting that THAT time-period is SHOWN to
BEGIN at 4:1 [and 6:2 upon the earth, unfolding] (
and END at His Second Coming
to the earth Rev19),
one can PRECISELY TRACE OUT exactly "2520 days" AS ON A "CALENDAR" (specific calendar-date to specific calendar-date to specific calendar-date... and yes, ON A CALENDAR);
...for one small example,
Rev8:1-5 is describing what takes place
ON ONLY ONE SPECIFIC CALENDAR-DATE... and in that "future," specific, LIMITED time-period (
what we call "the Trib"), the 144,000 "SERVANTS of our God" (of one nation: Israel) will be among the first to "UNDERSTAND" these very things (they will have come to faith in Christ
FOLLOWING "our Rapture"... so I'm not saying these are UNSAVED [/unbelieving] of Israel).
Once one sees it, one cannot UNSEE it (meaning, the ENTIRE "7 year period" MAPPED OUT on the CALENDAR, in Revelation!... Not just this one "example" I supplied.)
It just so happens to AGREE with Dan9:27:a,b,c[,26b]... "for ONE WEEK [7 yrs]"; but ALSO with the "beginning... middle... end" (
in the same way) as all OTHER passages covering this Subject.
