I am not (and I never have been) a fan of Joyce Meyer. A family friend of our's, Josh at Delivered by Grace, has written an article worth reading regarding this lady and others like her.

Unfortunately, many of these false teachers are abundantly available on the television programs of T.B.N. and other affiliates across the world.
