24 "When a corrupting spirit is expelled from someone, it drifts along through the desert looking for an oasis, some unsuspecting soul it can bedevil. When it doesn't find anyone, it says, 'I'll go back to my old haunt.' 25 On return, it finds the person swept and dusted, but vacant. 26 It then runs out and rounds up seven other spirits dirtier than itself and they all move in, whooping it up. That person ends up far worse than if he'd never gotten cleaned up in the first place."
Matthew Henry's Commentary on Luke 11:24-26
Commentary on Luke 11:14-26
(Read Luke 11:14-26)
Christ's thus casting out the devils, was really the destroying of their power. The heart of every unconverted sinner is the devil's palace, where he dwells, and where he rules. There is a kind of peace in the heart of an unconverted soul, while the devil, as a strong man armed, keeps it. The sinner is secure, has no doubt concerning the goodness of his state, nor any dread of the judgment to come. But observe the wonderful change made in conversion. The conversion of a soul to God, is Christ's victory over the devil and his power in that soul, restoring the soul to its liberty, and recovering his own interest in it and power over it. All the endowments of mind of body are now employed for Christ. Here is the condition of a hypocrite. The house is swept from common sins, by a forced confession, as Pharaoh's; by a feigned contrition, as Ahab's; or by a partial reformation, as Herod's. The house is swept, but it is not washed; the heart is not made holy. Sweeping takes off only the loose dirt, while the sin that besets the sinner, the beloved sin, is untouched. The house is garnished with common gifts and graces. It is not furnished with any true grace; it is all paint and varnish, not real nor lasting. It was never given up to Christ, nor dwelt in by the Spirit. Let us take heed of resting in that which a man may have, and yet come short of heaven. The wicked spirits enter in without any difficulty; they are welcomed, and they dwell there; there they work, there they rule. From such an awful state let all earnestly pray to be delivered.
