A. Good question! Many would say no; but I must say yes! The reason why so many say no, is because of a misunderstanding of scripture. In (1 Corinthians 2:6-8) Paul is talking about the difference of worldly wisdom even that of the mature rulers and Godly wisdom. Which is revealed through mystery. In v. 8 we read, "which none of the rulers of this age knew; (God's Wisdom) for had they known, they would not have crucified the Lord of glory." This clearly has nothing to do with the devil not knowing! Only the difference between wisdom of the world and the wisdom of God through his followers. Let me ask you some questions and judge for yourself. Does Satan know the word of God? Yes! Does he know the 300 old testaments prophesies of the coming messiah? Of course! Is that why he put in the heart of Harod to kill all children under 2? Yes! Herod and the wise men even knew he was, (Matthew 2:1-4)! Did Satan not personally temp Jesus during his fast? Saying "if thall be the son of God"?Yes!(Matthew 4:3) Stop! Jesus never spoke a word of him being the son of God until after he came down from the fast and went into his ministry (Matthew 4:17). Or let me ask you this. How can most all of Satan's demons cry out and call Jesus "Lord", "Thou art the Son of God", "What have I to do with thee, Jesus, thou Son of the most high God"? (Mark 5:7-13) (Mark 3:11)... Also keep in mind that the man with the legions, "was possessed with the (devil)", (Mark 5:15). So again, how is it that all these unclean spirits who report to Satan and are under his command knew who Jesus was; but yet Satan did not? Keep in mind, Satan was the most craftiest in the garden. So in my scriptural judgment, I believe he did know! Just a misunderstanding of scripture.
