Well we can not hold unsaved people to the same standard as those of us who by Gods grace have had their eyes open, I am not a fan of Oprah. But I can not say if or if not she is a witch. I know only God knows the heart and only He can truly change the heart. Hope God opens her eyes to the truth and she walks through the door of salvation. Remember it is only by Gods grace that we are following after Him and working out our salvation.
