Sorry, Q, you didn't answer my question.
It depends. Many prayers are witchcraft . . . in that they are a magical sort of thinking and incantation of the pray-er's wishes, rituals, constructions on reality with little commitment to, submission to God Almighty as the GrantOR of the answers to said prayers. They treat God more as a vending machine and expect Him to comply because the PRAY-ER has jumped--to their mind--through all the right hoops--therefore, God must answer accordingly.
That's a variation on witchcraft. I think some Scriptures would indicate such an assessment in such cases. Don't have the refs off the top of my head here at pottery.
Did not Jesus heal by prayers?
Of course He did--IN THE CONTEXT OF AN INTIMATE RELATIONSHIP WITH FATHER, PRAYING ACCORDING TO FATHER'S WILL. Huge issues and factors.
Or did He use "magic?"
Or were they mere witch doctors?
