Regarding Rick Warren and Joel Osteen

Churches today are fooled by the likes of Rick Warren and Joel Osteen because they admire only that which is popular, instead of truth, instead of the true mystery of God's words.
No doubt these great authors have written some very motivational books, however, it is the way they present what they have LEARNED themselves, which makes their works popular, not great, but popular. Like magicians who are very good at keeping their secrets.
