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
