The antichrist is actually known to both God and Satan.
The antichrist is actually Satan's son - the second part of the Satanic Trinity.
He has been ready to go - and is ready right now. To step in and do whatever his wicked father tells him to do.
But "it is the last time" and it will be the Antichrists time very soon . . . . and if you are here when he is revealed you will love him and worship him and mark yourself for him. You will hate anyone that does not love him. You will shout for joy at his amazing accomplishments. He will be the perfect Satanic imitation of Christ - with beauty, power, and miracles.
But with this one little, tiny difference: he will not have died for you. He will not have paid for your sins. Your believing in him? While it makes you feel good will not save you from your sins. It will send you to a Christ-less Lake of Fire.
