You know, we can’t be. Personally, I think the best reading is pre-trib and I hope it’s right and I’d LOVE to be around for it, but if I’m not, I’m not.
My believing that it’s pre-trib isn’t going to make it so. If it’s mid-trib or post-trib, that’s what it’s going to be.
We read Scripture, come to the best conclusion we can about it, and let God do what he’s going to do. If we’re wrong, we’re wrong. There’s nothing anyone can do about it other than live our lives in such a manner that whenever it comes and whatever happens, we’re ready.
