What did the Lord Jesus Christ do to the devil?

The Bible says that the Lord Jesus destroyed the devil when he died. This proves that the devil cannot be a great evil monster, who is alive today.

Our Lord had a human nature just like us, and he was tempted to sin just as we are. This means that the Lord Jesus had to struggle against “the devil” (his own natural desires) just as we do. But, unlike us, the Lord won every struggle; never once did he give in to temptation, and so “the devil” was defeated. Since Jesus Christ rose from the dead he has had an immortal body and no longer faces temptation. For him, human nature (“the devil”) has been destroyed and is dead.
