You would think that the adherents of the world's only true religion would also be the best people in the world. The Witnesses use the words "cultivate godly qualities" like a mantra, over and over. The believers feel that their attendance at meetings and their field service put them in line to gain God's favor as exceptional people.
The problem is that they aren't. There are plenty of kind, caring, generous, principled people in the world whose qualities way outshine the Witness's. I'm referring to people who actually go out of their way to serve their fellow-man with a view to the present and the future. On a large scale and in their own neighborhoods.
The Witnesses put those efforts down, trivializing the efforts by saying things like, "they are shoveling coal to keep the engines running on a sinking ship." Or, " their motives are not pure. They want to make a name for themselves."
But the Witnesses are forbidden to associate with "worldly" people, so they will likely never meet any of these good people.
