This is the warning of the Messiah that most of the Christians may ignore.
The Messiah has warned the disciples that the false Messiah and the false prophet will appear. And the false prophet will appear and perform great signs and wonders to deceive, if possible, even the elect. The Messiah has also warned us not to believe in the false prophet’s saying that the Messiah appear to him in the wilderness and the storerooms.
Paul was one of the false prophets because he could perform great signs and wonders. He also told the disciples that the Messiah appear to him on the road to Damascus in the wilderness and in the barracks. Unfortunately, Christians have been deceived and they believe in Paul more than they believe in the Messiah.
