Why should we be worried about all these? After the church is taken back to God I.e. Jesus comes in the air to receive the true Christians, then the spirit of the devil, spirit of Antichrist would be revealed at that time.Let us not assume things which we are not aware. Many will claim telling that they are christ.We are living in a sin full generation.
Who's worried?.....Your eschatology goes rapture first by the look, you've already made your assumption and that's fine. But I see 42 mths of the last 7yrs yet to come, these are the apocalypse years ahead for Christians by the hand of AC. After that 42 month period of Antichrist reign the church will be raptured I believe.
My scriptural base for my assumption is Rev 13:7, Gods Holy people are the Church washed in the blood of Christ are still here in the reign of Antichrist, Rev 13:9+10 explains the situation when we are persecuted at this point in time.
Rev 13:14 is very interesting because it says, "he deceived all the people who belong to this world," there is a definite distinction that he doesn't deceive believers that belong to God. It doesn't say all the people on earth it says "who belong" as apart from who don't IMO.
I think this leaves room to indicate we'll be around to witness these things, if not put to death, in prisons or the like, but it's just prior to the point of rapture imo. See Rev 6:9-11, with the focus on the final part of verse 11, this parallels the Rev 13 texts IMO and proves my interpretation accurate.
