Why does Satan fulfill the end time events that are written about him. He would clearly want to discredit the Bible, he would want to cause an event that would discredit the entire Word of God. Satan has had thousands of years and yet he has never been able to cast that shadow of doubt.
The law of sin and death is the real power of evil in the world but it is not interested in proving the Bible false, it simply opposes God word. Satan has convinced the world that the destruction law of sin and death produces is him. It makes him appear to be very powerful when in fact he is a defeated foe.
