We don’t know much about the seventy-two people who Jesus sent out to preach. What we do know is that he sent them two-by-two, that they were to go ahead of Jesus into all the towns he would be visiting, and that he told them to heal the sick in those towns and proclaim that the kingdom is near. We really have no idea who these people were, what their backgrounds were, or what professions they had. Jesus did tell them not to take anything with them except what was already in their possession.
When the seventy-two returned, they were astounded at what all God was accomplishing through them. “Lord!,” they exclaimed. “Even the demons are subject to us in your name!” (Luke 10:17 ESV). Jesus told them that he saw Satan fall like lightning from the sky, and that he gave the disciples authority over all the power of the enemy. It was an incredible responsibility that they were given. But Jesus didn’t want them to rejoice in this.
“Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven” (Luke 10:20). Jesus’ warning here was to not get intoxicated with the power they had. Sure, he gave them authority over the power of the enemy. But that didn’t make them invincible. Authority can be infatuating. It can lead to pride and arrogance. It can blind people to compassion. Jesus would rather them remain humble and rejoice that their names are written in heaven. This is a good reminder that our message needs to be seasoned with hope, grace, and must point people to salvation.
