The Antichrist is one figure, throughout Christianity and it's history, that many have been looking for. It's amazing just how many historical figures have been targeted with his name and as the Antichrist yet history has rolled on and proven each forecast to be wrong.
I have my personal beliefs where to look for the Antichrist and I'm also not certain that he will appear within our lifetime but I also certainly believe it could be our generation. There are many attributes assigned to the Antichrist among which are a great political leader, world leader, a very charismatic person as well.
Many protestant Christians, through the years and even today believe that the Antichrist, whomever he is, will come from the position of the Roman Catholic Pope and everyone knows his seat of power is Rome and the Vatican. I am not one who subscribes to this theory. I am not comfortable naming the Antichrist, at least as of yet, but I 100%, fully believe that the Antichrist will come out of Islam and be a Muslim. I believe that the Antichrist will be the Mahdi that Islam is looking to come, in their end days that will lead the world to become Muslim and will defeat the Jews and Christians and will have his seat of power in Jerusalem.
I can't say, with certainty, that it will be within our lifetimes but I do believe that there is that possibility given events as they are in the world today and how the future is trending with Islam growing, often at an unrestrained rate. That's just my own opinion.
