Here’s a quote from the answersinrevelation.org site:
“What if pretribulationists are wrong?
If pretribulationists turn out to be wrong, the consequences will be devastating as millions of Christians who expected a pretribulation rapture find themselves in the midst of the end time drama, facing the Antichrist!
Indeed, the evidence against the pretribulation view is staggering if people would simply allow themselves to be exposed to it. Yet, most refuse to even take a peek, and are constantly assured by their pastors and self-appointed TV prophecy experts that all is well. What are the shepherds going to say to the sheep if they have failed to prepare them for the roaring lion’s brutal attack?”
I am a staunch pre tribber. However if I am wrong and do find myself in the trubilation the only preparation I need is to be washed in the Blood of Jesus Christ and standing firm in His protection. That is already taken care of, no other prep to do. So don’t worry about us pre-tribbers, we will be fine no matter what.
