As John received revelation upon revelation sitting exiled upon the Isle of Patmos, he issued a very strong warning for us in our day. He told us that our entire world would be deceived (lied to) through the sorceries (perhaps many) that would come out of Babylon. (Rev. 18:23-24)
He went on to say that the end result of this deception would be the demise of prophets, saints and many good men. In other words no one would be spared in this great deception by these sorceries. Remember that we were told that, if it were possible, even the very elect would be deceived.
So what is this sorcery of which John warns?
