In 1993 when we were studying 1 Timothy chapter 4 our teacher then gave us five points on how we are to respond to untruths.
Let me share them with you.
1]We must know what this false teaching is.
2]We must not be afraid to condemned it.
3]We must show why it is wrong.
4]We must be faithful in guiding those we lead to proper response to these false teaching.
5]We must make sure that we are constantly exposed to the true teachings.
I have found two groups who are doing exactly this on face book.The are called Remove the false teaching from your christian bookstore's wall and Exposing false prophets-Reformation Christians against TBN.
