In the Gospel of Luke, Chapter 10, we read about Jesus sending out the seventy-two disciples. He sends them out with none of the usual things one would need for traveling. We are to understand that he does not want them to be attached to their possessions along the way.
Jesus gives them the power to fight off evil, using just his name and the power he has given.
When I think about this, I think about the mission each of us shares with the disciples. We, too, are to “go out” into the world and face evil and bring peace.
