Hello 2404;'Can the devil predict the future?' No, because he is not eternal but a time bound creature, subject to occurrences...
However he has much experience and all that data makes for a pretty good indicator as to an outcome. But the Lord being eternal is in control and makes the devil's every move work according to His plan. Even the fall has a purpose.
Good question. I think that answers to such question must come from the Scriptures themselves.
He can make educated guesses., by assessing peoples reactions on circumstances. He is smart but he not all knowing.
YES to Satan knowing the future. Actually, He know what You know. He has read the Bible and knows what it says about the future.
