Shalom! I've countered JWs (including family) with the refrain, "I'd love to be part of Jehovah's organization, so please prove to me with the bible the following and I will gladly harness up again........." Then lay it on to them, one at a time. If your spouse truely wants you to be "equally yoked" she will have the clear path to accomplishing her desire.. but you and I know a snowball in hell would have a better chance....
