It's for everyone, but it's not about everyone.
Either Christ's Olivet discourse is for His Church, or it is not. You cannot do that double-speak and be taken seriously.
It is for Christ's Church, especially His believers at the end of this world, because that... is the timing He was pointing to.
So the Pre-trib Rapture doctors (i.e., claimed scholars in the Pre-trib Rapture seminaries), treating Christ's Olivet discourse like it is not for Christ's Church, is actually a huge joke upon those willy-nilly enough to buy into it. As I've said in other posts, it is easy to spot doctrine from the devil in men's doctrines simply because it will not measure up with God's written Word. How so in this case you might wonder?
IF... Christ's Olivet discourse He gave while upon the Mount of Olives with His disciples is NOT for us, His Church, then those false prophets could also pick and choose all kinds of written Scripture directly by Lord Jesus in The Gospels, and say those Scripture aren't written for His Church either! And you know what, that is EXACTLY what some false prophets do that claim only Apostle Paul's Epistles are meant for and ABOUT Christ's Church.
But Christ's faithful Church well KNOW His Olivet discourse is for His Church, all the way up to His future return, SIMPLY because those Signs He gave parallel the Signs He gave in His Book of Revelation!
And who is Christ's Book of Revelation for? For CHRIST'S CHURCH, especially at the 'end' of this world. And it does not matter what Dispensationalists teach against that, for Apostle Paul also spoke of events about the end of this world related directly to Christ's Book of Revelation.
What a mess those false prophets have duped many brethren with, and it is mostly done in order to shore up their false Pre-trib Rapture theory!
