Hi I have been cured from hearing strange voices and been delivered from the po31wer of the demons after i did a 31 day fast on mostly juice fast. GOD told me to fast for 31 days and told me that i would be cured after the 31 day fast. On the 32 day of the fast which was the day I was going to be tormented I was not tormented so I was cured. You can fast for deliverance, to fight against evil.
