Don't Leave Your House Empty

Mar 9:25-27 LITV
(25) And seeing that a crowd is running together, Jesus rebuked the unclean spirit, saying to it, Dumb and deaf spirit, I command you, Come out from him, and you may no more go into him!
(26) And crying out, and convulsing him very much, it came out. And he became as if dead, so as for many to say that he died.
(27) But taking hold of his hand, Jesus raised him up, and he stood up.

I fear this relays a fundamental truth to us. If the evil was eradicated from the world, much of the world would have no life or movement at all. Things would grow deathly quiet. The only life this person had was demonic - to the point when it was cast out, the person appeared dead.

But then Jesus raised him up, and he stood. This is the Hope of Glory, when we are all raised up and we stand. Right now, evil is a present reality. We coexist with it. Jesus did what He commands us to do - run it off. But once we do this, we have to ask the Spirit of God to fill the void. Jesus later offers a warning:

Mat 12:43-45 LITV
(43) But when the unclean spirit goes from a man, he goes through dry places seeking rest and does not find it.
(44) Then he says, I will return to my house from which I came out. And coming, he finds it standing empty, swept and decorated.
(45) Then he goes and takes with him seven other spirits more evil than himself, and entering dwells there. And the last things of that man become worse than the first. So it will be also to this evil generation.
