Luke tells of Jesus’ temptation and of the beginning of Jesus’ ministry. Jesus goes to His hometown of Nazareth and is asked to read from an Old Testament scroll. Jesus lets them know the reading is about Him and His ministry on earth. They have been around Him since He was a boy and are horrified that one of their own would make such a claim. Jesus moves on to Capernaum, which will be His main location for much of His ministry. Jesus confirms that He is who He says He is by showing His power over demons and disease.
The chapter makes it clear that the powers of darkness are real. It could be in the form of temptation or direct power over a person. We need to stay close to Jesus and rely on the power of the Holy Spirit to battle Satan and his demons.
