First offer a beverage with a big smile

& offer them to have a seat; then ask this as is a most critical issue with groups like this is re: Authority:
What happened prior to 1879 when Russell founded their organization: in 1812, 1517, 516? Did God abandon the Christian world for soooo long? (We’re hit with Americans ex. Smith, Russell, White arriving very late on the scene to bail out the world! Really? How could a loving God ignore so many souls for 1900 years?)
If 2 of you disagree on an issue, where do you go to resolve your dispute? If elders is 1st answer, well, elders can disagree so who then? If Governing Body next answer, can they make mistakes? (my words: I have many JW books if you go to different editions that say polar opposite meaning of same sentence; some cases have even tweaked it back & forth; the men of Sodom is an example). So if GB gives a teaching, do you believe it no matter what? Can GB make mistakes? (see their books & changes) So, in the end if one has to
pray about whether to
accept their teaching, then congrats, YOU have made yourself your own POPE & you have
become what you DISLIKE! Do you know what you are saying?
- if they answer at any point “well, we could be wrong!”
That is the bottom line. They come & ask me to believe something based on doubt and could be "wrong". You have at this point offered your home, beverage, loving time & they offer DOUBT? Sorry, I trust in God and His Church and His Word which is Rock Solid! If they want to know more, come back next week!
(my thought here: for ex. I have 2 JW Bibles that say this about Jn 1:1…the Word was a god" (NWT) and “…the Word was God” (Byington edition published by WTBTS in the 80’s). I just have to point out a couple changes in the Book of John & there it is: DOUBT! So who resolves this doubt, it’s there in print & *again *I have many examples of what they have printed & changed. How could GB make such critical errors in the first place?- sounds confused to me & confusion is not of God. Discussing Mary, the Saints, hell, etc. Is MOOT; doesn’t matter at this point. Where did the basis for their existence, WHO established their Authority?).
Finally, offer to pray together with them & tell them you love them. Jesus Christ wished we should all be one didn’t He. Chances are they’ll pray just like us! Let them know that.
At the most fundamental level IF they see their concept of Authority is flawed (to my estimation it is indeed that), you’ve planted a
seed; hard to make the 800 lb. gorilla in the room go away! We are called to be seed planters; the Holy Spirit will do as He will
