It has been strongly suggested that the "falling away" as spoken by the Apostle Paul in 2 Thessalonians 2:1-4 is the pre-trib rapture.
We who are His Body, as Belonging to Christ, must know the His answer from His Word so as not to be decieved.
When the Disciples asked our Lord Jesus Christ about His Return(the Second Coming) He gave this immediate Commandment & Warning.
And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?
And Jesus answered and said unto them, Take heed that no man deceive you. - Matthew 24: 3-4
Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come.
Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God. 2 Thess 2:1-4
The Apostle Paul combines the clear warning of the Lord Jesus Christ in Matthew 24 with His Second Coming and the "Falling Away".
So is the "falling away" = the departure in the form of a pre-trib rapture or is it a "falling away" a departure from truth = the Gospel?
Human opinion alone on this important subject is not valid - Please confirm one way or the other with Scripture.
I make this Challenge for TRUTH = Prove it by the word of Two or Three Authoritative Witnesses = Matthew 18:16
2Th 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2Th 2:2 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.
2Th 2:3 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;
2Th 2:4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
The saints cannot be gathered unto Christ until the man of sin claims to be God which is in the middle of the 7 years period.
God is allowing the world 7 years to have their way and cause all people that do not love Him to follow the beast and then He will put the world down.
The reason the saints cannot be gathered unto Christ until the man of sin claims to be God is because repentance and salvation are still available for the first three and one half years and as long as salvation is available to the world the resurrection will not happen.
The falling away is the condition of the world in response to the Gospel which they stopped the preaching of the Gospel and nothing can be taught contrary to the new age movement interpretation of religion and reality.
After this goes on for three and one half years it is the falling away because the nations came together and stopped the Gospel from being preached which allows the man of sin to rule over them.
Islam rebels against the world which is the 6th trumpet and the world does not turn to God and repent of their sins so God gives them the man of sin to rule over them.
Islam rebelled because they stopped them from preaching their religion and the belief in a personal God.
