The reason that all people and not just the rich and powerful, will be calling to the rocks and the mountains to fall on them, is because 1) there will be a great earthquake...2) the sun will be darkened and the moon will be turned blood red, 3) stars (meteorites/asteroids) will be falling to the earth
(?) The text clearly states point-blank that they seek refuge in the rocks...not because of the earthquake...but to
"hide from the presence of Him who sits on the throne and from the wrath of the Lamb".
They had not been hiding in the rocks until this time because God's wrath had not made an appearance until this time.
The seals, trumpets and bowl judgments...
I would argue it is more clarifying to refer to 1) the seals and 2)
the contents of the scroll. It creates a demarcation. When the seven seals have been broken, only THEN are the contents of the scroll released. The contents of the scroll are God's wrath. The seals
are only leading up to God's wrath.
Matt.24:29-31 takes place 3 1/2 years [after the abomination of desolation] with Christ returning to the earth to end the age.
Wait a minute. You made a leap there...in concluding Jesus' return to earth is a full "3 1/2 years" after the mid-point event, "the abomination of desolation".
Think carefully: Jesus quotes from these famous OT passages about the sun and the moon darkening and explains these cosmic disturbances occur mere moments before He sends His angels to "gather the elect" in a supernatural translation (i.e a rapture).
But these same OT passages make it clear the Day of the Lord does not begin until
AFTER the occurrence of these great cosmic disturbances:
Joel 2:31 -- "I will display wonders in the sky and on the earth, blood, fire and columns of smoke. The sun will be turned into darkness and the moon into blood
BEFORE the great and awesome day of the Lord comes."
Therefore, these cosmic disturbances are happening well back from the end of the 3 1/2 years...in order to make room for the time of God's wrath.
Not to mention...if people living in those last days (probably us, by the way!) knew the Lord would be arriving 1260 days after the Abomination of Desolation...
they would therefore know the very day of the Lord's return...something He has specifically said is NOT possible. No one knows "the day or hour".
Therefore, the Lord
CANNOT be returning after 1260 days...and add that to the fact of Joel 2:31 clearly indicating ALL the events of the Day of the Lord only follow AFTER these spectacular cosmic disturbances.
Therefore, these cosmic events
MUST occur sometime during the second half of the 70th Week and
WELL before the end of those 1260 days.
In Matt.24:29 the sun and moon are darkened and the stars fall from heaven to the earth, but at the 6th seal an earthquake is mentioned with the sun being darkened and the moon turning blood red.
Just because the various "cosmic disturbance" passages in the OT and NT do not use the exact same words to describe the various facets...isn't an indication these are different events.
Even right within a single chapter, Joel 2, where these events are described twice (verse 10 and verses 30-31), there are a number of differences. Verse 10 merely says the moon becomes "dark". Verses 30-31 describe it as turning blood-red.
It the same with the synoptic Gospels (Matthew,Mark, Luke) where many of the same stories occur in all three books but invariably use different wording and include certain aspects that are NOT included in the other two accounts. No one concludes these are three different stories...but merely the same story described from slightly different perspectives.
Joel 2 - verse 10:
Before them the earth quakes,
The heavens tremble,
The sun and the moon grow dark
And the stars lose their brightness.
Joel 2 - verses 30-31:
I will display wonders in the sky and on the earth,
Blood, fire and columns of smoke.
The sun will be turned into darkness
And the moon into blood
Before the great and awesome day of the Lord comes.
