Jesus casts out a demon from a dumb (cannot speak) person. He is accused of casting out demons in the name of Beelzebub, "the Prince of Devils." He asks, "If Satan is divided against himself, how shall his kingdom stand?" Well, of course, we know it WON'T stand - we've read the book and Jesus wins!
Jesus also cautions that once the unclean spirit is cast out of a person, that spirit wanders around looking for a new place to rest - and not finding any, it sees the soul it once inhabited, and it is all cleaned and swept, so the unclean spirit returns and brings with it seven other spirits even more wicked and thus the last state of the person is worse than the first! Be on your guard! When you have just gone to Confession and have had your "house cleaned" - you are vulnerable to being re-inhabited and potentially be in a worse state than before! Remain strong in your prayers! When you sense temptation returning, pray even harder that you not be turned! Again, so much for the Protestant notion of Once Saved, Always Saved...
