How can Satan drive out Satan? If a kingdom is divided against itself, that kingdom cannot stand

Mark 3:20-35

When his family heard about this, they went to take charge of him, for they said, “He is out of his mind.” And the teachers of the law who came down from Jerusalem said, “He is possessed by Beelzebul! By the prince of demons he is driving out demons.”

“How can Satan drive out Satan? If a kingdom is divided against itself, that kingdom cannot stand. If a house is divided against itself, that house cannot stand.  And if Satan opposes himself and is divided, he cannot stand; his end has come.  In fact, no one can enter a strong man’s house without first tying him up. Then he can plunder the strong man’s house. Truly I tell you, people can be forgiven all their sins and every slander they utter, but whoever blasphemes against the Holy Spirit will never be forgiven; they are guilty of an eternal sin.”

“Here are my mother and my brothers! Whoever does God’s will is my brother and sister and mother.”

Why?

The crowd gathered around Jesus because they want to be healed their sick and solve their problem. But Jesus came to save us from sin is the first priority, next is to love people, heal their sick, drive out Satan, 

Jesus explained that he is not come from Satan, for a kingdom of Satan will be divided. Jesus can drive satan for he came from heaven.

For Jesus is the savior, so whoever does God's will is brother and sister and mother of Jesus. We are a family of the Lord. This is a new identity in Spirit.

How?

Jesus is the Lord, and through Jesus we could be a family of the Lord. Trust Him and believe Him and obey His commands.
