And he was preaching in their synagogues throughout all Galilee, and was casting out demons.
This verse briefly presents the ongoing course of Christ’s ministry in Galilee. His work united teaching and action, word and power. By preaching in the synagogues, he addressed the people in the centers of their religious life, and by casting out demons, he showed that his word is confirmed by real deliverance. Together these two aspects testify that the kingdom of God is not only a truth that is taught, but also an active power that breaks the dominion of evil.
