according to mark 3:20-35

Jesus exposes an absurd accusation

3:20-21 Then he went indoors, but again such a crowd collected that it was impossible for them even to eat a meal. When his relatives heard of this, they set out to take charge of him, for people were saying, "He must be mad!"

3:22-27 The scribes who had come down from Jerusalem were saying that he was possessed by Beelzebub, and that he drove out devils because he was in league with the prince of devils. So Jesus called them to him and spoke to them in a parable - "How can Satan be the one who drives out Satan? If a kingdom is divided against itself, it cannot last either. And if Satan leads a rebellion against Satan - his days are certainly numbered. No one can break into a strong man's house and steal his property, without first tying up the strong man hand and foot. But if he did that, he could ransack the whole house.

3:28-29 "Believe me, all men's sins can be forgiven and their blasphemies. But there can never be any forgiveness for blasphemy against the Holy Spirit. That is an eternal sin."

3:30 He said this because they were saying, "He is in the power of an evil spirit."

The new relationships in the kingdom

3:31-32 Then his mother and his brothers arrived. They stood outside the house and sent a message asking him to come out to them. There was a crowd sitting round him when the message was brought telling him, "Your mother and your brothers are outside looking for you."

3:33 Jesus replied, "And who are really my mother and my brothers?"

3:34 And he looked round at the faces of those sitting in a circle about him.

3:35 "Look!" he said, "my mother and my brothers are here. Anyone who does the will of God is brother and sister and mother to me."
