I think Mormans and JW's are in error because they believe that only their particular groups can go to heaven. I totally disagree with their doctrine, but I realize that most of them go door to door because they are concerned for the eternity of others. They deserve a respectful, "No thank you. I appreciate your concern for me and I know it's not easy what you're doing, but please don't come back." I do share my faith, but it is through relationships and kindness to others. People who do not share my beliefs are my friends regardless if they never want to hear about my faith. They are not projects or forms to be filled out.
