A clean house doesn’t matter if no-one lives there.

Luke 11:14-26

Who lives in your heart? If it's Jesus, he's not roommates with the devil. In fact, the child of God--indwelt by the Spirit of God--ought to be demonstrating the power of God is every day living! Jesus had a lot to say about this to a group religious people who knew a lot about religious politics, but very little about the actual power of God.
