Right, they refused to believe in His authority and the look at the bigger picture, this was not his first time dealing with those guys, Pharisees.
Are you another who does not consider context and the bigger picture?
I am using the entire context.
24 Now the Pharisees, hearing it, said, "This man is not casting out the demons except by Beezeboul, the chief of the demons."
25 Now, having perceived their sentiments, He said to them, "Every kingdom parted against itself is being desolated, and every city or house parted against itself shall not stand."
26 And if the Satan is casting out the Satan, he is parted against himself. How, then, shall his kingdom stand?
27 And if I, by Beezeboul, am casting out demons, by whom are your sons casting them out? Therefore they shall be your judges."
28 Now if, by the spirit of God, I am casting out demons, consequently the kingdom of God outstrips in time to you."
29 Or how can anyone be entering into the house of the strong one, and plunder his gear, if ever he should not first be binding the strong one? And then he will be plundering his house."
30 He who is not with Me is against Me, and he who is not gathering with Me is scattering."
31 Therefore I am saying to you, Every sin and blasphemy shall be pardoned men, yet the blasphemy of the spirit shall not be pardoned."
32 And whosoever may be saying a word against the Son of Mankind, it will be pardoned him, yet whoever may be saying aught against the holy spirit, it shall not be pardoned him, neither in this eon nor in that which is impending."
