strange thing that Christians disagree about.

The apostle Paul clearly states a pretrib rapture to the Thessalonians prompting them angst that they had already missed it.

1820 my foot.

These new converts shortly after Christ's earthly ministry saw daily life taking place as normal but suspected that the secret event happened leaving them behind. Where did they get the idea of a secret rapture that they had missed?

Don't give me Matthew 24. That is specifically to the "Jew" and I believe it is for after the man of sin is revealed.

By the way, Christ will resurrect us, the only people who concern themselves with the rapture are the living which the graveyards are already full of Christians already passed and room for more.

Worry about salvation.
