The hard thing is your wife is confinced she is right because that is what the JW's taught her. Challenging her concepts, especially challenging the words like "Unbeliever", or "Worldly Person", you need to point out to your wife those are words used to try and put a division between JW's and other Christians or people of other faiths. You need to let her know that she is never to refer to you as an unbeliever or a worldly person to your children ever. It makes anyone they make that comment about to be something less important or acceptable to God. They are not representing God exclusively except in their own perception which does not make it correct.
Garyneal you handled your wife very well, keep her challenged. Never ever force your daughter to go to the JW meetings and your wife should never be allowed to make comments about people calling them worldly people, that is insulting and rude. Love your wife unconditionally and if she doesn't share in activities with you and your daughter let her know what she missed. The witnesses love to say that Jesus came to cause division of father against son, mother against daughter etc., (Matthew 10:32-38) like that is something to be expected in being a Christian.
Matthew 10:32-38 (New International Version)
32 "Whoever acknowledges me before men, I will also acknowledge him before my Father in heaven. 33 But whoever disowns me before men, I will disown him before my Father in heaven.
34 "Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword. 35 For I have come to turn
" 'a man against his father,
a daughter against her mother,
a daughter-in-law against her mother-in-law -
36 a man's enemies will be the members of his own household.
37 "Anyone who loves his father or mother more than me is not worthy of me; anyone who loves his son or daughter more than me is not worthy of me; 38 and anyone who does not take his cross and follow me is not worthy of me.
Something JW never mention is that down in Matt 10:40 it shows that the above scriptures refered to rejection of Jesus as the spokesman from God. That was the only condition to accept Jesus as a Prophet of God and his followers who preached about it. It does not say anything about an organization speaking out for Jesus.
