cults

I found out recently that a friend of mind had joined the Adi Da (Bubba Free John) cult, which is a nasty cult where the leader declares himself to be god. For that, I would just quote this from the Bible, Matthew 7:
"Watch out for false prophets; they come to you looking like sheep on the outside, but they are really like wild wolves on the inside. You will know them by their fruits. Thorn bushes do not bear grapes, and briers do not bear figs. A healthy tree cannot bear bad fruit, and a poor tree cannot bear good fruit. "Any tree that does not bear goof fruit is cut down and thrown into the fire. "So, then, you will know the false prophets by their fruits."
