The "Falling Away" is scripture. The rapture is not. To clarify as simply as possible, the falling away is the 1/3 that Satan gets because they were deceived by the false doctrine of the end times. Rapture is nowhere in God's word except when described as false doctrine and "God hates those that would teach his children to fly to save their souls". We are not going to fly away from the tribulation, we are to testify and teach during that time. The one who stays in the field doing God's work means the one who does not run to worship the false christ.---- The unforgivable sin is to NOT let the Spirit speak through us during the trials and tribulation. ----God's Kingdom will be established here on Earth after the cleansing. Why would you want to go anywhere else. Where would you be going if Christ is here? Being "Caught up with Christ" in the air means to be ascended to our spirit form, not flying away from the battle between good and evil. ----The man of sin will be revealed to be the false christ after that 1/3 has been claimed by Satan. If he was revealed before that, then no-one would fall for his lies would they. We must remember that antichrist comes at the 6th trump and will be revealed BEFORE Christ establishes his Kingdom on Earth. Christ doesn't return until the 7th trump. Read and learn God's word for yourself and listen to him, not man.---- Beware of modern translations of the bible, they have clearly been written to fool Christians into falling for the rapture theory. Compare those scriptures that you believe prove rapture to the old bibles and you will clearly see the deception. God will bless those who are patient like he told us to be. May your studies be blessed with understanding of God's truths and warnings.
