"They also like the blood guilt verses from Eziekiel. I am sure I spelt that wrong."
They do...but I think it was in the same chapter that God commande Ezekiel to use shit as fuel when baking his bread. I wonder what a JW-baker wold use?
There is some reasons for preaching. First, Rutherford realised that bookstores would never distribute the WT-litterature, so the only way to sell it was by door to door sale.
The preaching keeps people busy. They invest time, effort and emotion in it, that mekes them tighter connected to the org.
