The preacher was speaking of the zeal but it is the truth of scriptures that must be spread not the erroneous interpretation of men who say you must come to them for salvation..there is a scripture in the bible that states "speak not in the ears of a fool for they will dispise your wisdom". JW's are taught not to argue with anyone about religion. Alot of non-JW's want to argue about everything. I once had a preacher tell his congregation that if everyone spread the word of God like the JW's does, the world might be a better place.<quoted text>
You can bet your life he wasn't talking about the lies they spread to the innocent that don't know scriptures well enough to spot the false, twisted scriptures that glorify an org rather than Jesus or God.
