23 And turning to them, he said to them in the form of a story, How is it possible for Satan to put out Satan? 24 If there is division in a kingdom, that kingdom will come to destruction; 25 And if there is division in a house, that house will come to destruction; 26 And if Satan is at war with himself, and there is division in him, he will not keep his place but will come to an end. 27 But no one is able to go into the house of the strong man and take his goods, without first putting cords round the strong man, and then he will take his goods.
Matthew Henry's Commentary on Mark 3:23-27
Commentary on Mark 3:22-30
(Read Mark 3:22-30)
It was plain that the doctrine of Christ had a direct tendency to break the devil's power; and it was as plain, that casting of him out of the bodies of people, confirmed that doctrine; therefore Satan could not support such a design. Christ gave an awful warning against speaking such dangerous words. It is true the gospel promises, because Christ has purchased, forgiveness for the greatest sins and sinners; but by this sin, they would oppose the gifts of the Holy Ghost after Christ's ascension. Such is the enmity of the heart, that unconverted men pretend believers are doing Satan's work, when sinners are brought to repentance and newness of life.
