Lk 9:1-6
1[Jesus] summoned the Twelve and gave them power and authority over all demons and to cure diseases, 2and he sent them to proclaim the kingdom of God and to heal [the sick]. 3He said to them, “Take nothing for the journey, neither walking stick, nor sack, nor food, nor money, and let no one take a second tunic. 4Whatever house you enter, stay there and leave from there. 5And as for those who do not welcome you, when you leave that town, shake the dust from your feet in testimony against them.” 6Then they set out and went from village to village proclaiming the good news and curing diseases everywhere.
Jesus Summoned the Twelve: Jesus is called Rabbi (Teacher) by many of his followers. Here, we get a glimpse of his ways. While prospective students of the law usually choose the teacher under whom they will study, Jesus’ followers are handpicked by him (Lk 6:13). The Twelve are not only mathetai, followers and companions of Jesus in his ministry. They are apostoloi, people who are sent on a mission (Lk 6:13). Jesus expects them to continue his work when he returns to the Father.
Jesus then goes about preparing the Twelve for their mission. He gives them specific instructions so that they will know what to do. He tells them how to cope with tough times. Above all, Jesus empowers them—he passes on to them his authority. The expression “power and authority” is repeatedly used by Luke to refer to Jesus’ own ability to rebuke both demons and diseases (4:36; 5:17; 6:19). Encouragement without empowerment is enthusiasm without
direction. Jesus himself is the recipient of his Father’s trust and empowerment.
