The apostasia is not the rapture.

2 Thessalonians 2:1 would actually refer to that, if indeed there is a rapture. It depends how you read verses 1 and 2.

“coming of the Lord Jesus Christ”

WHAT IS APOSTACY? apostasia
Possibilities: defiance, rebellion, abandonment, a breach of faith, or a betrayal.

It’s either rebellion against normal civil order (This is the view shared in our Eschatology Man of lawlessness video) WATCH VIDEO HERE: https://youtu.be/JXmIynCa90Q

or it’s rebellion more specifically against God and God’s truth. Which is the position this video takes.
