Evil is never static. It must defend its lies by adding more lies. Legalism is like garlic; there is no such thing as a little of it. If a few people in a church hold false doctrine, they will get more and more followers, unless sternly dealt with. William MacDonald, Believer’s Bible Commentary, Galatians 5:9
This is why I firmly believe pastors should expose false teachers regularly from the pulpit; tell the flock about the poison they will find in the Christian book stores and on the TV! Expose the Gothards, Ezzos, Pearls, the Beth Moores, the Benny Hinns, the Joel Osteens, etc! Expose Strategic Level Spiritual Warfare and Deliverance Ministries! Report on the Emergent church!
Too many pastors say all we have to do is teach the truth so they will recognize error, but experience has proven that to be totally inadequate. There are too many cultish teachers and groups who have a very tasty outer shell which hides poison on the inside. Sometimes the doctrine is good but the application is heavy with legalism. EXPOSE IT FOR WHAT IT IS!!!
