My daughter, through kindness, led her teenage friend out of her JW study. It took her a few months, but the love paid off.
On the other hand, KLS, I hear what you are saying, babe. I have seen woman doormats, trying always to turn the other cheek, displaying Christian kindness, only to see their own needs and desires ignored. I don't think Jesus' commands meant that we needs must be silent about our own desires. A marriage relationship may be the most intimate partnering we ever do. I find my marriage to be a lot more work than being a parent. At least as a parent, it was clear about who was in charge....me! A marriage relationship must be balanced, and both partners must feel free to talk about what is bothering them. Otherwise, the partner suffers.
I do find that the same meek, mild presentation style that the JW's use to be most effective to get a JW to listen. That doesn't mean the words themselves have to be mild. I have delivered some of my most devastating comments in a mild and calm manner. This type of self-control is very much admired by JW's and ordinary people alike, so it has a good chance of being heard.
