I can not remember anything in the Bible, that said the book of Revelations would be the end of God's word to man. At the same time, I know there are many parts to the accounts in the Bible, that were not put in or are not accepted as inspired by God. With this in mind, what if your morning started like this;
You wake up, the room is all dark and a man who is glowing is standing at the end of your bed. He tells you that he is a messenger from God and needs you to write down dome dire warnings, and information that must be spread to the world. You grab a piece of paper, and listen, and as you do so he shows you images of the world being destroyed and shows you that the world is soon to end. He leaves, and you find out that it has been several days and it was only feeling like a few hours to you. You believe so strong in what happened, that you write every second of your memories down and prepare yourself for telling the world, thinking of how you will do it.
What do you think would happen?
Most likely you would find yourself laughed at, you would find yourself scorned for being to extreme, and soon if you took it too far, you might find yourself locked in a padded room with pills to make you calm down. Wouldn't you agree, this is how the world would see your amazing morning. Even if what you saw was real to you, and the message was something that you honestly felt all mankind was meant to hear?
Isn't it amazing, how much this same type of story would have been accepted thousands of years ago and found people willing to listen and die for it. Yet if the same thing happened today, it would be something considered a joke, and insanity. For this reason, I think that in modern times, it has become about what religions existed prior to this day to choose from. Any new religion, new supernatural event (supposed), or any new books from God, would be immediate seen as insane or people trying to do something to control man to their own dire outcome. Interesting, when you think about it, what really has advanced so much in mankind that new religions are not possible anymore?
