Here's an interesting tidbit from John MacArthur on how to deal with false teachers.

So if you agree with John MacArthur, free willism is false teaching and comes under the classification of being "the other religion of the world".

Hebrews 11:6 says that without faith it is impossible to please God. So if free-willism states that we can choose to have faith of our own free will, then free-willism states that we can, in and of ourselves, please God.The Two Religions of the World
Because of the many religious bodies existing in the world today, people are easily confused about how to differentiate them. But when you think about it, there are really only two religions in the world: the religion of divine accomplishment-- that God in Christ accomplished salvation apart from any effort of man--and the religion of human achievement--that men attain to salvation by something they do. The religion of divine accomplishment is the Christian gospel. Every other religion in the world in one way or another fits into the category of human achievement. Wherever false doctrine strikes a blow at the gospel, it will purport that man in and of himself can please God.
So if you agree with John MacArthur, free willism is false teaching and comes under the classification of being "the other religion of the world".
