My concern with this thread is not the content. On the content I have no comment especially since I didn't read it all. My disagreement is with the title saying a certain thing will damage our very souls. Specifically anyone who believes in pretrib has a damaged soul. In effect the writer is saying that if you don't interpret the book of Revelation the way I do you are in trouble, which is in itself a dangerous thing to say, not to mention extremely presumptuous. He didn't need to say that in order to make his case. We need to be more careful with our words and our judgements.
We are not the subject of Revelation, we are the recipients. It is obvious that Revelation is not chronicle. It speaks of things that had happened before it was written, things that were happening, things that hadn't happened yet but now have and things that haven't happened but will, not necessarily in that order. It is an overview of who Jesus is, what He has done and what He continues to do. We learn that Jesus is all authority and power ( thus He is God, the second person of the Trinity. Not secondary but second in order) that He controls all things and ordained all things, is the Alpha and Omega, the beginning and the end. That the world is in terrible shape through our rebellion and it will get worse but His people, those who trust in Him, will be safe. It gives us comfort that no matter what we have to go through in this part of our life, He has us beneath the shadow of His wings, He will bring us safely home. It promises us that He will return at some time unknown to us and restore all things. How we interpret the signs and symbols and timeline in Revelation does not affect our souls. The only thing that damages our souls is not trusting in Jesus for salvation.
The title of this thread could pull a believer towards believing the given interpretation in order to be saved and cause them to miss the whole purpose of Revelation. It won't affect his salvation if he is a true believer, but it could make him afraid. Be careful.
