The devil thought he was defeating Christ, but Christ was reconciling us to God, defeating the devil and delivering us out of his clutches.
Here is one of the most wonderful things about the cross. Here is one of the most glorious reasons for glorying in the cross. Here Christ defeated our ultimate enemy, the devil, the one who originally brought man and the universe down. He was cast out, he was defeated. He has been put in chains. And finally, he is going to be completely and utterly destroyed. He will be cast into the lake of fire with the beasts and all the false prophets. And he will have no more power.
