I've always been told that when Jesus died on the cross, he ultimately defeated Satan and won victory over death. Satan was not aware of the secret plan and thought that he had defeated Jesus until Jesus died and he realized what had really been going on.
I don't find that so hard to believe, but I've been thinking about it lately ... Since there are a lot of prophecies about the son of God in the Old Testament -- and Jesus fulfilled them all -- shouldn't it have been quite clear for the Devil that God's plan was to sacrifice his only son, namely Jesus, on the cross to cleanse all of our sins? I figure that he should have the necessary intelligence to come to that conclusion. Or is it something along the lines that he's not able to understand the ways of love and truth, since he hates love and truth and all that is good, and has nothing to do with any of it?
So, my question is: Was Satan really taken by surprise when Jesus died on the cross?
