yes Jesus did give us signs mentioned in Matthew 24, Mark 13 & Luke 21, but some people think we are still in the birth pangs & that they will intestify as Jesus return draws near, there are some pastors who think the 7 seals & the 4 horsemen are happening right now, then there are others who think the 7 trumpets are blowing, it all depends on what view of the end times you believe in
It should... depend on what is actually written in God's Word, and not... what we'd like to believe. It's important that the Bible student first be aware of how they can be misled, either by their own lack of Bible study, or by heeding doctrines of men.
It is common for those who open up Christ's Book of Revelation in study and think the events happen in the order that John saw them and wrote them down. But that is not entirely accurate.
What Christ's Olivet discourse shows us is that there are only 7 Signs of the end, the last Sign being that of His coming and gathering of His faithful Church. And since the Seals in Revelation 6 follows the very order of those 7 Signs He gave in Matthew 24 and Mark 13, reveals something deeper.
It reveals the 7 Seals, 7 Trumpets, and 7 Vials are actually only about those same 7 Signs. And when we look at the last Sign in His Olivet discourse, that of His future coming, we see that last Sign is also the 6th Seal, the 7th Trumpet, and the 7th Vial timing. (the 7th Seal I see as a statement of completion, much like how the word 'Selah' is used in the Psalms).
Now I can't give a play-by-play with all those Seals, Trumpets, and Vials linked together, but I can with the very last ones that point to the day of Christ's future return and His cup of wrath being poured out upon the wicked, and the heavens rolling up like a scroll, and the hills and mountains and islands passing away.
Thus Christ's coming is on 777.
