Mark 3:25

Mention has been made of the unclean spirit whom the Lord shows to be divided against himself. The Holy Spirit, however, is not divided against himself. Rather he makes those whom he gathers together undivided against themselves, by dwelling within those who have been cleansed, that they may be like those of whom it is written in the Acts of the Apostles, "The multitude of them that believed were of one heart and of one soul."

(Vict. Ant. e Cat. in Marc.) The blasphemy of the Scribes having been detailed, our Lord shows that what they said was impossible, confirming His proof by an example. Wherefore it says, And having called them together unto him, he said unto them in parables. How can Satan cast out Satan? As if He had said, A kingdom divided against itself by civil war must be desolated, which is exemplified both in a house and in a city. Wherefore also if Satan's kingdom be divided against itself, so that Satan expels Satan from men, the desolation of the kingdom of the devils is at hand. But their kingdom consists in keeping men under their dominion. If therefore they are driven away from men, it amounts to nothing less than the dissolution of their kingdom. But if they still hold their power over men, it is manifest that the kingdom of evil is still standing, and Satan is not divided against himself.

He refutes the hateful Jews with irrefutable examples. How is it possible, he says, for a demon to cast out demons, when even in ordinary houses we see that as long as those living in them are at peace, the houses stand well, but as …

And if a house be divided against itself,.... Any family, small or great, that house cannot stand; its contentions and discords will soon bring it down from a comfortable and flourishing situation, to a very distressed one; See Gill on Mat 12:25.

We all know how painful it is to have our conduct misunderstood and misrepresented, when we are doing right. It is a trial which our Lord Jesus Christ had to endure continually, all through His earthly ministry. We have an instance in the passage before us. The "Scribes who came down from Jerusalem" saw the miracles which He worked. They could not deny their reality. What then did they do? They accused our blessed Savior of being in league and union with the devil. They said, "He has Beelzebub, and by the prince of the devils casts he out devils." In our Lord's answer to this wicked accusation, there are expressions which deserve special attention. Let us see what lessons they contain for our use. We ought to notice, in the first place, how great is the evil of dissension and divisions . This is a lesson which is strongly brought out in the beginning of our Lord's reply to the scribes. He shows the absurdity of supposing that Satan would "cast out Satan," and so help to destroy his own power. He appeals to the notorious fact, which even his enemies must allow, that there can be no strength where there is division. "If a kingdom be divided against itself, that kingdom cannot stand." This truth is one which does not receive sufficient consideration. On no point has the abuse of the right of private judgment produced so much evil. The divisions of Christians are one great cause of the weakness of the visible church. They often absorb energy, time, and power, which might have been well bestowed on better things. They furnish the infidel with a prime argument against the truth of Christianity. They help the devil. Satan indeed is the chief promoter of religious divisions. If he cannot extinguish Christianity, he labors to make Christians quarrel with one another, and to set every man's hand against his neighbor.
