Jesus makes everything practical.
In Mark 3:20-30 Jesus is accused of driving out demons by the power of another demon. He refutes this by using logic.
"How can satan drive out satan?"
"A kingdom divided cannot stand."
He then switches His focus to the gospel by using a parable, something practical to describe what will happen.
"In fact, no one can enter a strong man's house and carry off his possessions unless he first ties up the strong man. Then he can rob his house. I tell you the truth, all the sins and blasphemies of men will be forgiven them. But whoever blasphemes against the Holy Spirit will never be forgiven; he is guilty of an eternal sin."
He said this because they were saying, "He has an evil spirit."
(This unforgivable sin is essentially this - Rejecting Jesus and the Holy Spirit)
But the focus of this parable is on the gospel. The devil has taken people captive and caused destruction. The devil is the strong man. What does it take to tie of a strong man?
A stronger man.
Jesus came to proclaim freedom for the prisoners (Luke 4). Jesus is the stronger man! When you see the forgiveness Jesus offers, your heart will be free and your conscience clear.
Jesus does not carry empty words. His words have power and authority and he shows this parable in action.
Mark 5:1-20 -There was a demon possessed man. No one could subdue him because he was too strong. He even broke chains that people tried to shackle him with. We was out of his mind and naked because of the demons .
But what happened when he saw Jesus? He ran and fell on his knees in front of Jesus!
What does it take to tie up a strong man? What does it take to make a strong man bow down?
A stronger man.
Jesus sent the demons out of the man and set him free. Once he was in his right mind he sat calmly at Jesus' feet clothed. Jesus told him, "Go home to your family and tell them how much the Lord has done for you, and how he has had mercy on you."
What does it take to empower someone to be strong?
A stronger man.
This newly freed man left and proclaimed what the Lord had done for him not just to his family, not just to his city, but to 10 surrounding cities.
That is the power of the stronger man. He is Jesus.
