Faithful or Saltless?
Faithful disciples will receive great rewards, but those who harm their weaker brethren risk condemnation to Gehenna . John complained because someone who was not from among their inner circle was casting out demons in Christ’s name. However, if this outsider was doing so, then it was God who was acting through him. John’s complaint was rich in irony since just a few verses earlier the disciples found themselves unable to exorcise demons because of their unbelief.
