22 Then a demon-possessed man, who was blind and couldn't speak, was brought to Jesus. He healed the man so that he could both speak and see. 23 The crowd was amazed and asked, "Could it be that Jesus is the Son of David, the Messiah?" 24 But when the Pharisees heard about the miracle, they said, "No wonder he can cast out demons. He gets his power from Satan, the prince of demons."
Matthew Henry's Commentary on Matthew 12:22-24
Commentary on Matthew 12:22-30
(Read Matthew 12:22-30)
A soul under Satan's power, and led captive by him, is blind in the things of God, and dumb at the throne of grace; sees nothing, and says nothing to the purpose. Satan blinds the eyes by unbelief, and seals up the lips from prayer. The more people magnified Christ, the more desirous the Pharisees were to vilify him. It was evident that if Satan aided Jesus in casting out devils, the kingdom of hell was divided against itself; how then could it stand! And if they said that Jesus cast out devils by the prince of the devils, they could not prove that their children cast them out by any other power. There are two great interests in the world; and when unclean spirits are cast out by the Holy Spirit, in the conversion of sinners to a life of faith and obedience, the kingdom of God is come unto us. All who do not aid or rejoice in such a change are against Christ.
