How can Satan cast out Satan? If a kingdom is divided against itself, that kingdom cannot stand. And if a house is divided against itself, that house will not be able to stand. And if Satan has risen up against himself and is divided, he cannot stand, but is coming to an end. But no one can enter a strong man’s house and plunder his goods, unless he first binds the strong man. Then indeed he may plunder his house.

As I stared at this chapter for a few moments, it dawned on me how often Jesus' teaching provides the central theme in a passage. Our eyes are drawn to the red letters, not because they are somehow more inspired than the narrative verses, but because Jesus is the main character. Like any well-written piece of literature, the main character often carries the message of the book, and this is no exception. It is only fitting that the all-knowing Son of God, who was living directly in the middle of this chapter's action, would provide a concise and penetrating commentary on what is going on around him.
So, what is going on around him? People are being healed of incurable diseases. Evil spirits are quite clearly and vocally being driven away from the oppressed. Some people respond to these miracles by crowding around Jesus, almost crushing him (3:9). Others, including his own family, think that he is out of his mind (3:21). The religious leaders especially make their opinion loud and clear: "He is possessed by Beelzebul" (3:22). He is accused openly of relying on Satan to do his work (notice how they were looking for a reason to accuse him all along - 3:2).
So, how does God in the flesh, the Creator of the Universe, respond to these venomous hearts of stone?
He gives them logic.
We know that Jesus was a little angry and grieved by their hard hearts (3:5), but he responds with self-control, using a rhetorical question that is meant to discredit them to the core. "How can Satan cast out Satan?" Of course, you fools! Don't you see that your doubts and skepticism and accusations and oppositions comes not from a righteous interest in the glory of God, but rather from an arrogant self-righteousness that cares only for its own reputation. It boils down to petty jealousy, a verdict that the Gospel writers often make note of.
Even as I write this, I think about the times when I have let accusatory thoughts boil and churn in my mind concerning some brother or sister in Christ. Verse 3 penetrates me so deeply when I read it because I know my own tendencies to look for reasons to accuse. It's ironic really, because as the religious leaders accused Jesus of working by Satan's power, it was really them all along who were tearing down themselves and others by the power of the evil one. When we dwell on the mistakes and failings of those around us, we are not only being unforgiving and wasting a lot of time, but we are doing the devil's work. How can we, who claim to cast all our hope on the humble Son of God, turn from his throne of grace and seek to blame and condemn our fellow believers? Perhaps a quiet hour meditating on the mercies of God (Rom. 8) or thinking through the folly of judgmentalism (Rom. 14) would be a good place to start.
Or, maybe we can start in Mark 3, by meditating on the Man who poured out his life in healing the weakest of the weak so that our Enemy would be forever bound and his unholy house forever destroyed. May we turn to our Savior, who not only holds the staff of comfort, but the rod of protection, to keep us from the evil one. And we know too, that "lo, his doom is sure," as Luther so powerfully sang:
And though this world, with devils filled, should threaten to undo us,
We will not fear, for God hath willed His truth to triumph through us:
The Prince of Darkness grim, we tremble not for him;
His rage we can endure, for lo, his doom is sure,*
One little word shall fell him.
That word above all earthly powers, no thanks to them, abideth;
The Spirit and the gifts are ours through Him Who with us sideth:
Let goods and kindred go, this mortal life also;
The body they may kill: God’s truth abideth still,
His kingdom is forever.
*see Rev. 12:12 and 20:7ff.
