Rapture is a new doctrine, only a few if hundred years old. Where the New Testament talks about the "resurrection" is turned into to mean the rapture by biblical publishers who have an ulterior motive.
The rapture is the counter doctrine of the Anti-god for the resurrection. God's salvation is the "difficult way," the narrow road where God takes you through your trials to overcome your fear. The Anti-god's salvation is the easy way, where he gives you a license not to pay your sacrifice so as to NOT go through your trials.
