1 Thessalonians 4:15-17 this is the scripture that everyone bases the concept of the rapture on
15 For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
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.
The rapture itself is the coming of the Lord.
and for clarity, Paul had to write a second letter to the Thessalonians, because they weren't clear on how this was going to work out. Basically you had pretribbers and post tribbers and preterists claiming it'd already happened etc, and Paul had to explain it to them.
2 Thessalonians 2:1-3
2 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
Paul again, equates the concept of the rapture, as happening when the Lord returns, and gathers us to Him, and tells us that the abomination of desolation has to happen first.
So what do we have in the Thessalonians epistles?
A falling away
The man of sin
The return of the Lord from Heaven
a trumpet
Gathering the saints to Him.
Now Matthew 24, let's break this down
there's a falling away in Matthew 24:10-12
10 And then shall many be offended, and shall betray one another, and shall hate one another.
11 And many false prophets shall rise, and shall deceive many.
12 And because iniquity shall abound, the love of many shall wax cold.
then the man of sin revealed in Matthew 24:15
15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand
then the return of the Lord from Heaven, in the clouds in Matthew 24:30
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.
and finally the trumpet and the gathering of saints to Him in Matthew 24:31
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.
This is the same event, and it is also depicted in Revelation 6 after the 6th seal, and another view of it is depicted in Revelation 14:14-20. Note that the first angel that harvests, does not put that harvest in the winepress of God's wrath, they're just harvested.. After they're harvested, there's another harvest of what remains.. and these are put into the winepress of God's wrath. You're right that we see the result of the rapture in Revelation 7. But you're wrong about that being before the 70th week. The 70th week had been going on for at least 3.5 years before the rapture, as the abomination of desolation takes place at the midpoint, and the return of our Lord and our gathering together to Him doesn't happen until after that.
