The verse you quoted is referring to the coming of Jesus and it is the when He raises the dead and comes in glory.
1Th 4:16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
And that is why you err. 1 Thess.4:16-17 is the event of the gathering of the church, not the event of the Lord's return to the earth to end the age.
1 Thess.4:13-18 and 1 Cor.15:50-53, are referring to the gathering of the church
Matt.24:30-31 and Rev.1:7, are referring to the Lord's return to the earth to end the age.
Until you understand that these are two different events, which take place at different times and for different purposes, you will be in error regarding end-time events.
Revelation 19:6-8 shows the bride/church as already being in heaven attending the wedding of the Lamb. Then in verse 14, it shows the church following Christ out of heaven riding on white horses and wearing the same fine linen that she will have received at the wedding. Furthermore, we also have the following information regarding Christ returns to the earth to end the age:
In order to follow the Lord out of heaven, you would already have to be in heaven.
"They (beast and ten kings) will wage war against the Lamb, but the Lamb will triumph over them because he is Lord of lords and King of kings—
and with him will be his called, chosen and faithful followers.”
The words 'and with Him will be his called, chosen and faithful followers' would also demonstrate that the church will be returning with Him to the earth to end the age to confront the beast and his armies.
"Now Enoch, the seventh from Adam, prophesied about these men also, saying, “
Behold, the Lord comes with ten thousands of His saints, to execute judgment on all, to convict all who are ungodly among them of all their ungodly deeds which they have committed in an ungodly way, and of all the harsh things which ungodly sinners have spoken against Him.”
When the Lord comes, Ten thousands of His saints will come with Him, which is supported by the previous scripture when those who will have been resurrected, changed and caught up, will be following Christ out of heaven on white horses.
The basic principle remains in that, because Jesus already suffered God's wrath on behalf of every believer, satisfying it completely, God's wrath no longer rests upon the believer. We are not appointed to suffer God's coming wrath and therefore must be gathered from the earth prior to said wrath. Regarding this, Jesus warns us to watch ourselves so that we do not go back into the world to willfully living according to the sinful nature, so that the time of God's wrath which will be coming upon all who live on the face of the whole earth, will not close on us like a trap.
Furthermore, as a promise to all those who overcome and endure patiently, the Lord says that He will keep us 'out of' the hour of trial, that is going to come on the whole world to test the inhabitants of the earth. The 'hour of trail' is another name for the Day of the Lord, the time of God's wrath.
If you understood this basic principle and the severity of God's coming wrath, you would not continue to believe and teach that the Lord is going to put His bride/church through the time of His wrath. Anyone on the earth during that time will be exposed to the results of the seals, trumpets and bowl judgments, as well as the plagues that the two witnesses bring.
