24 Now when the Pharisees heard it they said, "This fellow does not cast out demons except by Beelzebub, the ruler of the demons." 25 But Jesus knew their thoughts, and said to them: "Every kingdom divided against itself is brought to desolation, and every city or house divided against itself will not stand. 26 If Satan casts out Satan, he is divided against himself. How then will his kingdom stand? 27 And if I cast out demons by Beelzebub, by whom do your sons cast them out? Therefore they shall be your judges. 28 But if I cast out demons by the Spirit of God, surely the kingdom of God has come upon you. 29 Or how can one enter a strong man's house and plunder his goods, unless he first binds the strong man? And then he will plunder his house. 30 He who is not with Me is against Me, and he who does not gather with Me scatters abroad. 31 "Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men. 32 Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come.

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.

Commentary on Matthew 12:31-32

(Read Matthew 12:31-32)

Here is a gracious assurance of the pardon of all sin upon gospel terms. Christ herein has set an example to the sons of men, to be ready to forgive words spoken against them. But humble and conscientious believers, at times are tempted to think they have committed the unpardonable sin, while those who have come the nearest to it, seldom have any fear about it. We may be sure that those who indeed repent and believe the gospel, have not committed this sin, or any other of the same kind; for repentance and faith are the special gifts of God, which he would not bestow on any man, if he were determined never to pardon him; and those who fear they have committed this sin, give a good sign that they have not. The trembling, contrite sinner, has the witness in himself that this is not his case.
