How do you get your wife to stop going to a Jehovah's Witness Kingdom Hall when she was born a Christian?
You can't really stop her. God gave people free agency, and she's using it to go to what ever church she desires. If you feel she should go to a Christian church then just show what an example Christian you are, but it's ultimately her decision. Answer::From a Jehovah's Witness Perspective You definitely can't stop her. Once you know Jehovah, absolutely no one can get in your way. I guarantee you. Please trust me. This may not be what you want to hear right now, but the best choice you will ever make is to go with her. Just one meeting and I promise you will want to go back. She's doing what she is suppose to be doing, so don't try to stop her, support her... and you will learn something. Answer: From a Christian Perspective If by being 'born a Christian' you mean born into a Christian home well, that doesn't make a person a Christian anyway as each person needs to receive Jesus Christ personally for themselves. Jehovah's Witnesses and other cults prey on those who 'go to church' but aren't really committed and don't know their Bible. The best thing to do is to study the Bible - a proper one, not the New World Translation and then the truth will stand out from the error.
There are also many ex Jehovah's Witnesses who may be able to help. It is important to pray and to be close to God oneself - going to the Kingdom Hall probably won't help as there are multitudes of books about Jehovah's Witness errors. The matter of free choice is certainly true - but the key is giving something against which to choose. If a person does not really know the truth they cannot discern error. Reading the Bible in its context and going to a good Bible-believing church will help also.
