What is wof? I keep seeing that, but never heard of it.
Word of Faith is, basically, taking teachings you find in New Age (a commercial form of occult) and wrapping those teachings in a bible wrapper, using out of context scriptures to justify the teachings to Christians.
Oprah promoted the same teachings, minus the Christian wrapper, and she is well known own as a New Ager.
The "Christian" version teaches having faith in faith, rather than faith in God. That what you speak into that faith will manifest into reality. And "God", the magic genie, will grant these wishes, as that is, apparently, His main purpose in life.
The New Age version is the same, but instead of "God" they claim it's "The Universe" that answers our words. The Universe is a cosmic, non-personal, god-type entity that is more of an idea than anything else.
The Christian version goes under terms such as Word of Faith, Name it and claim it, prosperity gospel, etc...
So if you want a BMW, all you need to do is speak it into existence and God (The Universe) will hear you, and with enough belief, eventually manifest one (literally).
They also teach Christians shouldn't never get sick, and if one does show the symptoms of it, to deny it.
For example, I remember my first encounter with this teaching as a teen. A girl showed up at my youth group with a cold, when I mentioned that she was sick she cut me off, told me she wasn't sick and that she didn't claim that and that I should not mention it again.
You see these teachings mostly in charismatic oriented churches or seeker sensitive churches.
Osteen is a rich television Preacher that ignores sin and teaches people to only care about the quality of their Own life while here on earth. And he teaches visualization, a form of the above teachings and the same teaching Oprah promoted. Which would explain why she promoted him and he so freely accepted this by going on her show.
