Preaching

While teaching in the Capernaum synagogue on the Sabbath, Jesus is interrupted by a demon-possessed man. Jesus then rebukes the demon, commanding it to shut up and get out of the man. After its violent exit, people in the synagogue are not only amazed with Jesus authoritative words, but astonished by His authoritative works. He proclaims the inbreaking kingdom of God in both word and deed

Because the appointed time has come, and the kingdom of God has come near, people should repent and believe in the gospel. Christ — the King — is both the message and the messenger. His first disciples exhibit the appropriate response to Christ’s radical claim: radical obedience

Three important experiences signify the inauguration of the kingdom of God through Jesus Christ — the King. (1) The heavens are torn open, (2) the Holy Spirit descends into Jesus, and (3) God’s heavenly voice speaks. God’s word confirm that Jesus is the royal Messiah, the unique Son of God, and the prophesied Suffering Servant.

Then, Jesus is driven out into the wilderness to be tempted by Satan — setting the stage for the spiritual battle that runs throughout Mark. 

Though scholars debate the length of the prologue, Mk 1:1-8 is largely about John the Baptist while Mk 1:9-15 is largely about Jesus. The transition from John the Baptist to Jesus the Christ (i.e., the Messiah) indicates the transition from the old era to the dawning of a new age in redemptive history.
