Cutting off all contact with the false prophet. This is absolutely crucial to your restoration if you have been victimized by a false prophet. Many saints make the mistake of keeping in touch with a false prophet, or continuing to watch/listen to their ministry programming, and this is a grave mistake because in so doing they are exposing themselves to the false anointing of that prophet and the spirits that accompany it.
Now, some will advocate forgiveness, and it is commendable to forgive. However, this doesn’t mean we should continue to expose ourselves to something unwholesome. If the prophet is continuing in operating in error, we can forgive without granting that person access to us. You could forgive someone for stealing your car, but that doesn’t mean you throw them the keys afterward, especially if you know they’re still stealing cars! Remember, we are to have no fellowship with the unfruitful works of darkness (Ephesians 5:11), and 1 Corinthians 5 does instruct us to shun those who claim to be brethren but who refuse to turn from sin.
