It's a simple little word, made all the more beautiful by that simplicity. If you think about it "no" is hat the heart of everything we "know". All that you say and do that is not directly related to Bible-believing teachers like myself should be based on this one expressive gift to mankind.
Today's liberals want to remove it from our vocabulary, and say "no" isn't needed today, but they are lying. A few church leaders still have the intestinal fortitude needed to say "no" to others in need, even if it makes them unpopular with those thrown about by every wind of doctrine Eph 4:14), and they're easy to recognise: they're GAFCON men.
Practice saying "No" regularly, and those around with will be certain of where you stand. They'll recognize you as a GAFCON bible-believer
