It was the experts during the Lord Jesus’ earthly ministry who were wrong about the most important subjects in Scripture. Jesus frequently demonstrated this by logically scrutinizing their claims. For instance, in Matthew 12 Jesus, addressing the Pharisees’ claim that he cast out demons by the power of the devil, made the following argument –
“Every kingdom divided against itself is laid waste, and no city or house divided against itself will stand. And if Satan casts out Satan, he is divided against himself. How then will his kingdom stand? And if I cast out demons by Beelzebul, by whom do your sons cast them out? Therefore they will be your judges. But if it is by the Spirit of God that I cast out demons, then the kingdom of God has come upon you.”1
Firstly, note that Christ logically scrutinized the claim that “it is only by Beelzebub, the prince of demons, that [he] casts out demons.”2 He drew out what is implicit to their assertion, namely that that there is a kingdom of demons of which the devil is the prince.
Secondly, note that Christ argued from the general to the particular as regards the nature of the kingdom of demons. Specifically, the Lord Jesus stated that every kingdom divided against itself is laid waste (i.e. is utterly defeated/reduced to ruins by its opponents 3). The word “every” is universal, which means that what Christ asserted applies to all kingdoms, including the kingdom of demons. Thus, if the kingdom of demons is divided against itself, it will be laid waste/utterly defeated/reduced to ruins by its opponents comprising the kingdom of heaven/the kingdom of God.
Thirdly, note what Jesus asked his opponents –
“...if Satan casts out Satan, he is divided against himself. How then will his kingdom stand?”
The kingdom of demons does not want to be laid waste. Why then would it oppose itself and seal its own doom? If there is a war between the two kingdoms, and kingdoms that want to obtain victory over their opposition operate as a united front, then this applies to the kingdom of demons as well. Consequently, if the kingdom of demons desires to obtain victory over the kingdom of God it will not be divided against itself.
Fourthly, Christ emphasized his point by asking –
“…if I cast out demons by Beelzebul, by whom do your sons cast them out?”
If the Pharisees believed that their sons cast out demons by the power of God, this implies that they agreed with Christ regarding whether or not a kingdom seeking to obtain victory over its opposition would be internally divided. Thus, Jesus went on to state –
“Therefore they will be your judges.”
Christ, essentially, argued that if the Pharisees believed their sons cast out demons by the power of God, then they agreed that the kingdom of demons is a unified front against the kingdom of God. But if the kingdom of demons is a unified front against the kingdom of God, then it cannot be the case that Jesus cast out demons by the power of the devil. If the Pharisees claimed their sons cast out demons by the power of God, then they tacitly admitted their blasphemous claim about Christ was ipso facto false. Jesus refuted their claim, reducing it to absurdity, but also demonstrated the utter hypocrisy of the Pharisees.
Lastly, Christ drew out the logical consequence of what the Pharisees tacitly admitted to when they claimed their sons cast out demons by the power of God. He stated –
“…if it is by the Spirit of God that I cast out demons, then the kingdom of God has come upon you.”
The assertion here follows the Lord Jesus’ emphasis on the implied unity of a kingdom as it attacks an opposing kingdom. If the nature of kingdoms in general is to seek victory over their opposition by presenting a unified front against them, then it follows that the kingdom of God does the same. Whoever opposes the kingdom of demons, therefore, is on the side of the kingdom of God. Moreover, note the significance of Christ’s assertion –
“…if it is by the Spirit of God that I cast out demons…”
If it is not an evil spirit, namely the devil himself, who is empowering Christ to cast out demons, then it can only be the Holy Spirit who empowers him to do so.
The response given by Christ not only addresses the blasphemous foolishness of his enemies, it also implicitly teaches that the Holy Spirit is a divine person. Whereas the Pharisees said that Christ’s actions demonstrated he had an unclean spirit,4 he stated that his actions demonstrated that through him the kingdom of God had come upon his enemies. Christ is not possessed by an unclean/unholy, intelligent, volitional, and morally deviant agent who can indwell humans and cause them5 to sin – viz. an unclean spirit; rather, he is filled with, and guided by, the clean/holy, intelligent, volitional, and morally pure agent who can indwell humans and cause them to live righteously – viz. the Holy Spirit.
Christ could have given an elaborate Scriptural argument demonstrating why the claim of his opponents was false. Instead, he took their claim and drew out its logical consequences. And his disciples followed suit.

5 While we are all ultimately responsible for our sin, Christ teaches that men can be caused to sin, by which he means they can be urged and encouraged to sin by wicked men, in Matt 18:5-7.
