My favorite pastors believe in a pretribulation rapture. I currently attend a church that holds to a pretrib eschatology. So, my disagreement with this view is no reflection upon anyone’s faithfulness to God. In fact, I normally like pretribbers more than post-tribbers.
However, as your brother in Christ, I am required to point out where you get things wrong, especially if such errors put you in harm’s way.
Just remember what I wrote last week about our tendency to blindness. We are all vulnerable to error, and it’s hard to undo the mistakes that we were taught.
