Revealing the error of those who follow a false doctrine from men instead of heeding God's Word as written, is NOT sarcasm.
But you have not shared anything in this thread yet to prove it is a false doctrine. Just saying it is a false doctrine without reproof by scripture is hardly going to progress anywhere in this discussion.
I can... explain that, but can you explain the Matthew 24:29-31 Scripture where Jesus showed His coming to gather His saints is AFTER... the tribulation?
First off, is noticing His disciples were asking Jesus 3 questions.
Matthew 24:1And Jesus went out, and departed from the temple: and his disciples came to him for to shew him the buildings of the temple. 2 And Jesus said unto them, See ye not all these things? verily I say unto you, There shall not be left here one stone upon another, that shall not be thrown down. 3 And as he sat upon the mount of Olives, the disciples came unto him privately, saying,
Tell us, (#1) when shall these things be? and (#2 ) what shall be the sign of thy coming, and ( #3 ) of the end of the world?
As you read down that chapter, do note Jesus is not answering those questions in chronological order since He is not talking about when that Temple they are seeing will get thrown down right away which was the first question they had asked Him.
There is tribulation and then there is great tribulation. Jesus is describing the latter days as tribulation in Matthew 24:4-13 before the great tribulation comes which is after the gospel is preached everywhere for when the end shall come in Matthew 24:14-22. Jesus goes back and forth on this for why discernment and wisdom is needed from the Lord to see the truth in His words.
** Side note Actually, Matthew 24:14 is about when the end comes ( the disciples 3rd & last question ) as that first angel will do that as being of the 3 angels that sets up the hour of temptation that shall try all upon the earth in Revelation 14:6-11 which Revelation 14:1-5 testifies of, out of those raptured, 14,000 virgin men makes His personal choir that follows Him around wherever He goes in Heaven.
Anyway...read about how Jesus went back to before the great tribulation again and was describing the "tribulation" of those days before His appearing in Matthew 24:23-27 below as He did started out that way in Matthew 24:4-5 about deceivers.
Matthew 24:23 Then if any man shall say unto you, Lo, here is Christ, or there; believe it not. 24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. 25 Behold, I have told you before. 26 Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. 27 For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be. 28 For wheresoever the carcase is, there will the eagles be gathered together.
Then apply your reference below as confirming that is when He shall appear after the tribulation of those days when believers are going astray.
29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: 30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. 31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
One could say at or after the rapture event, the first angel preaching the gospel everywhere signifies how the end will come as Jesus said in Matthew 24:14 for answering that 3rd question "
of the end of the world"
