In these verses we see Jesus healing people of sickness and driving out more demons. The demons it seems all knew who He was, yet Jesus really wasn’t going to rely on the testimony of the agents of Hell to spread the good news; He ordered them to keep quiet. Even when He retreated to a solitary place, the people found Him and tried to persuade Him to remain with them, but Jesus couldn’t do that, for He had come to spread the good news of the Kingdom of God all over
Let’s just keep this short and sweet: When Jesus preached the good news of the Kingdom of God, what happened?
First, people were amazed at the authority with which He spoke about it. Second, people were healed both of their illnesses and their spiritual oppression, both of which are things that came about as a result of Man’s falling away from fellowship with God. Third, Jesus gave practical confirmation of His authority; that it had indeed come from God. Yet there is another element in all of this, an apocalyptic element. Jesus demonstrated in physical terms what would soon happen in eternal terms after He had dealt with the sin of humanity and restored fellowship between Man and God, and if memory serves me, Luke also wrote a volume in which he told that story.
