How can there be a “falling away” after the rapture? The Church is gone from this world after the rapture. The falling away is before the rapture. What you are seeing, and I also, are true believers beginning to stand apart. Sure there will be those who God has called who prior to now have not been vocal but those will be few imo.
Perhaps that's what I've been seeing.
The believers are becoming more determined, for lack of a better term.
