Matthew 12:25

Every kingdom divided against itself is brought to desolation - Our Lord's argument was thus: - "The welfare of any kingdom, city, or family, depends on its concord and unanimity; Satan, like every other potentate, must wish to rule his empire in peace and security; how then can he be in league with me, who oppose his authority, and am destroying his kingdom?"

The reasoning of the Pharisees, Matthew 12:24, was not expressed, and Jesus, knowing their thoughts, gave them ample proof or his omniscience. This, with our Lord's masterly confutation of their reasonings, by a conclusion drawn from their own premises, one would have supposed might have humbled and convinced these men; but the most conclusive reasoning, and the most astonishing miracles, were lost upon a people who were obstinately determined to disbelieve every thing good, relative to Christ. How true the saying - He came unto his own, and his own received him not!

And Jesus knew their thoughts ... - To know the thoughts of the heart belongs only to God, Psalm 139:2; Jeremiah 17:10.

Every kingdom ... - Their subtle and cunning device was completely foiled, and Jesus made their argument recoil on their own heads. A kingdom or a family can prosper only by living in harmony. The different parts and members must unite in promoting the same objects. If divided - if one part undoes what the other does - it must fall. So with the kingdom of Satan. It is your doctrine that Satan has "possessed" these whom I have cured. It is also your doctrine that he has helped me to cure them. If so, then he has helped me to undo what he had done. He has aided me to cast himself out - that is, to oppose and discomfit himself. At this rate, how can there be any stability in his kingdom? It must fall, and Satan must have less than human prudence.

12:25 Jesus knowing their thoughts - It seems they had as yet only said it in their hearts.
