“He drives out demons by the power of Beelzebub, the chief of demons,” (Lk 11: 15) this was how the scribes and Pharisees described the healing miracle of Jesus freeing a dumb man from an evil spirit and enabling him to regain his speech. Instead of seeing the intervention of God’s saving power, they maliciously doubted the authority of Jesus.
Logically speaking, would the devil undo itself and what he has done? Why would the evil one drive away its own kind? In doing so, evil divides its own kingdom, defeating himself and his kind. It is a contradiction: it would not happen.
The enemies and detractors of Jesus were so blind, with hardened hearts and minds, that instead of seeing and believing, they questioned and refused to see. Why? Because they refused to believe Jesus and his works; they did not have faith.
In the Gospel reading, Jesus invites us to see and read God’s intervention and salvation in his actions and not to be so biased to refuse to see because we were already prejudiced and had already made pre-judgments, despite the facts and evidence.
