John Wesley on Matthew 12:27

By whom do your children - That is, disciples, cast them out - It seems, some of them really did this; although the sons of Sceva could not. Therefore shall they be your judge - Ask them, if Satan will cast out Satan: let even them be judges in this matter. And they shall convict you of obstinacy and partiality, who impute that in me to Beelzebub, which in them you impute to God. Beside, how can I rob him of his subjects, till I have conquered him? The kingdom of God is come upon you - Unawares; before you expected: so the word implies.
