Mark 1:29-39 Jesus drives out demons even though they know him

On leaving the synagogue
Jesus entered the house of Simon and Andrew with James and John.
Simon's mother-in-law lay sick with a fever.
They immediately told him about her.
He approached, grasped her hand, and helped her up.
Then the fever left her and she waited on them.

When it was evening, after sunset,
they brought to him all who were ill or possessed by demons.
The whole town was gathered at the door.
He cured many who were sick with various diseases,
and he drove out many demons,
not permitting them to speak because they knew him.

Rising very early before dawn,
he left and went off to a deserted place, where he prayed.
Simon and those who were with him pursued him
and on finding him said, "Everyone is looking for you."
He told them, "Let us go on to the nearby villages
that I may preach there also.
For this purpose have I come."
So he went into their synagogues, preaching and driving out demons
throughout the whole of Galilee.

In this passage, Mark gives us a snapshot of Jesus' Ministry. It is clear that Jesus healed the sick, he exercised people of demons, he prayed, and went from village to village preaching. This is his ministry which took place after his baptism which lasted about three years until he was crucified. Although some may dispute his divinity, scholars all agree that he was a real person who actively ministered to the communities around him. Another interesting note is that in the passage about driving out the demons, the demons knew he was the Son of Man and Jesus prevented them from speaking. This goes back to the tradition that if a demon knew your name it could control you. If you knew the demon's name you can control it. Here, the demon knows Jesus' true identity and yet he is able to control the demon, making him a super demon crusher.
