25 Jesus knew their thoughts and replied, "Any kingdom divided by civil war is doomed. A town or family splintered by feuding will fall apart. 26 And if Satan is casting out Satan, he is divided and fighting against himself. His own kingdom will not survive. 27 And if I am empowered by Satan, what about your own exorcists? They cast out demons, too, so they will condemn you for what you have said. 28 But if I am casting out demons by the Spirit of God, then the Kingdom of God has arrived among you. 29 For who is powerful enough to enter the house of a strong man like Satan and plunder his goods? Only someone even stronger-someone who could tie him up and then plunder his house. 30 "Anyone who isn't with me opposes me, and anyone who isn't working with me is actually working against me.
Matthew Henry's Commentary on Matthew 12:25-30
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.
