Jesus continues healing and doing many wonders. He heals Simon's mother-in-law from a fever, as well as others with various illnesses and diseases. He even continues casting out demons and demonstrating his authority over the world of unclean spirits. The crowds attempt to keep him from departing, but Jesus tells them that it is necessary for him to go and proclaim the good news of the Kingdom of God to other towns. In fact, he tells them that this is the purpose he was sent for!
The crowds seem to want Jesus to stay with them because it will be for their advantage. A guy who can cure sicknesses and cast out demons is pretty handy to have around. But Jesus will not be reduced to a good luck charm. Like we saw earlier in Luke's gospel with Jesus in the Temple as a boy, he is very clear on the purpose for which the Father has sent him. Are there times that you think about Jesus primarily in terms of what he can do for you and neglect the proclamation of the good news of the Kingdom for which Jesus came?
