Luke 11:18 (KJV)

What does Luke 11:18 mean?

Luke 11:18 records Jesus challenging the claim that He casts out demons by the power of Beelzebub (a name for a demonic ruler), arguing that if Satan were working against himself, his own kingdom could not survive. Jesus points out that a divided force cannot stand, so the accusation against Him does not make sense.

In this scene, Jesus is speaking to a crowd that includes critics who accuse Him of using evil power to perform exorcisms. He uses simple logic: if Satan (the chief adversary) is divided and fights against himself, his rule would collapse. This argument exposes the flaw in their accusation and sets up Jesus’ teaching about the true source of His authority.

The Greek behind Luke 11:18

• Σατανᾶς (Satanas, "Satan"): This word refers to the adversary or accuser, a spiritual enemy in Jewish and Christian thought. Jesus uses it here to point to the supposed ruler of the demonic realm.
• διαιρεθῇ (diairethē, "divided"): This verb means to be split or separated. Jesus’ point is that internal division destroys any group or kingdom, including Satan’s.
• βασιλεία (basileia, "kingdom"): This word means a realm or reign. Jesus frames Satan’s influence as a kind of kingdom, making the logic of unity and division easy to grasp for His listeners.
• Βεελζεβούλ (Beelzeboul, "Beelzebub"): This name was used for a chief demon or the “prince of demons.” The accusation was that Jesus was using this evil power, which He refutes.

Why Luke 11:18 matters

• Luke 11:18 clears up the misunderstanding that Jesus’ power over demons could come from an evil source by showing the logical impossibility of such a claim.
• The verse highlights Jesus’ ability to reason with His critics and turn their accusations into an opportunity to teach about the nature of good and evil.
• This moment connects to the wider passage, where Jesus goes on to explain the true source of His authority and the importance of being aligned with God rather than divided.
