Benny Hinn is an agent of Satan. His "power" is not from God, its a power and spirit from Satan. Many times Hinn is on record giving so called prophecy or other messages from God yet they all turn out to be false, that is not the actions of a genuine person working with GOd.
One example, several years ago Hinn came over to UK and held one of his events in Wembley. Someone from my church went to see him. Hinn said that God had given him a message to give to the Christian of UK, it was a serious message which told of a terrible time and Christians in UK would suffer terribly by the end of the year.
In order to hear this message people were told they could hear it the following day at a special dinner event at about £200 per head. I was present when the person phoned to say they wanted help to pay for this. The Church said no we would not pay for her. She did not like that.
Anyway, nothing did happen to the Christians of UK at end of year, Hinn never said sorry, but no doubt enjoyed the extra thousands he took for people to hear this false message.
Hinn is a pawn of satan, it maybe he is unknowingly, or maybe not, but whatever it is, people should not follow HInn, that is one road to disaster.
