We just finished a wonderful weekend retreat at our house using Ken Fish's Intermediate Healing videos. Not as many people as had originally said would come were actually able to attend, but the Lord worked through the few. Those of us who attended were encouraged to follow Jesus' command to His disciples to heal the sick, cast out demons, raise the dead. and were given tools to help with this. This type of ministry is SO needed today because it doesn't seem many have learned about it which is another reason it is so needed! There are so many hurting people who don't know where to turn to get help.
I heard Ken Fish say he is writing a book on the Integrated Healing Model. It will be very welcome when it is released! I feel Ken has an excellent understanding of how healing the body, soul and spirit are related and must be addressed before a person can be totally healed. I highly recommend checking out his website: Kingdomfireministries.org
