While there may also be consequences in our lifetime to obeying the adversary, the eternal consequence of trusting in Yeshua, as our Messiah and Deliverer are enjoying magnificent security, safety, and God’s chesed (merciful love) that can never be taken away from us
When the Antichrist shows up during the time of Jacob’s trouble, he will fool people into thinking that he is actually the Messiah, Jesus Christ. Antichrist has the title of Messiah, ‘Christos’, built right in his name, he is just a false messiah. But this is exactly who is being sung about in the Exsultet prayer at the Vatican, it has nothing to do with the real Messiah, Jesus.
Now C.S. Lewis does cover more eloquently how free will and an omniscient God could exist at the same time, could these great men and what I added be refuted?
