The Word of Faith movement is a loose coalition of false teachers, all of whom teach that faith is a force, that words contain that force, and that by believing the right things and speaking the right words, we can change reality itself. Ultimately, these ideas suggest that humans are divine in nature and can do all that God can do.
Steven Furtick is a very popular speaker, a gifted communicator, and – based on the growth of his congregations – likely a gifted leader as well. He has a great amount of influence and a worldwide audience. Of course, those have nothing to do with whether he’s a false teacher.
