I am sharing some points from the notes I took. For the most part, he brought out some good biblical points. What I'm sharing with you, however, are hard for me to take with a wink and a nod. Please note that these points are taken from my notes the way I heard them. Also, I feel like these are excellent suggestions, but there are plenty of articles in the WT publications that contradict them:
-Let our speech identify us as being different...as servant's of God.
-We should not speak disparingly about someone who doesn't share our
beliefs.
-Never should we lose the quality of humility and modesty.
-Never show a superior attitude.
-Be respectful to others.
So many stupid people, so few comets! :o)
