Matthew 12:22-32

Blasphemy against the Spirit
Parallels at Lk 11:14-23 and Mk 3:22-30, see also Mt 9:32-34.
v.22-23 Jesus healed a demon possessed man who was blind and mute. The people were amazed and wondered if this man (Jesus) could be the long-awaited Messiah (son of David). This is another fulfillment of Is 35:5-6 (the eyes of the blind shall be opened, etc.) and one that is readily verifiable.
v.24 Even in the face of undeniable miracles the pharisees refused to believe. They blasphemously attribute the healing to Beelzebub, the prince of demons (i.e., Satan). Contrast this with the demon’s testimony that Jesus was the Son of God (Mt 8:29).
v.25-26 Satan does not fight against Satan; otherwise his kingdom would not stand. Jesus acknowledges that there is a spiritual world where Satan exists. The Pharisees acknowledge that demons can possess people and work supernatural things through them.
v.27-28 It is not clear what is meant by the Pharisees’ sons casting out demons. Perhaps some ritualistic ceremony was performed by some of the Pharisees’ followers. Ellison (ZBC) indicates that some prominent rabbis served as exorcists. The crowds were amazed at Jesus commanding demons out with a word (indicating that the Pharisees’ followers were not as successful). But if it is instead by the Spirit of God that Jesus drives out the demons, then the kingdom of God has come upon them.
v.29 One cannot plunder a strong man’s house without first binding the strong man (like i.e., Satan). This further indicates the error in the Pharisees thinking and indicates that Jesus is stronger than Satan (so he can bind him). Jesus’ ministry was not hindered by Satan because he could not hinder it. Jesus came to release those under Satan’s power of darkness.
v.30 There is no neutral ground, either you’re for Jesus or your working against God and his plan. But see Mk 9:38-41.
v.31-32 These verses address the unforgivable sin: which is refusing to accept the unambiguous and clear work of God and attributing it to Satan. Such sin will not be forgiven.
