The disciples were jealous. Nine of them together were unable to drive out a single evil spirit, but when they saw a man who was not one of their group driving out demons, they told him to stop. Our pride is hurt when someone else succeeds where we have failed, but Jesus says there is no room for such jealousy in the spiritual warfare of his kingdom. Share Jesus’ open-arms attitude to Christian workers outside your group.
John said to Jesus, “Master, we saw someone using your name to cast out demons, but we told him to stop because he isn’t in our group.” But Jesus said, “Don’t stop him! Anyone who is not against you is for you.” (Luke 9:49, 50 NLT)
