Appreciate Jolted Awake comments. If someone chooses the path of atheism, it must be a personal decision. A person cannot be coerced through preaching it. But if one is a true believer, the best thing that you can do is show that the hope remains the same, but who you put your trust in changes.
I agree with the scriptural proof Jolten Awake uses. I know this is wise advise, simply because I would of been that type of person if my wife discovered TTATT first. But my life has been VERY smooth, because I went from being a JW to being a relaxed Christian that maintains many of the core doctrines of the Watchtower. Namely, God's purpose for the earth, what the kingdom is, God is not a trinity, God's name is Yahweh.
Some may think I am preaching when I share these websites. However, this is not the case. I share these, because many feel like I do, in that the Watchtower has some truth. That is what they use as a lure. Then the propaganda begins. Many have "no place to go".
But by discovering that others believe similarly, but with no high control, a person does not feel so alone. It is due to discovering these, that has brought great peace to my house. It comforts my wife to know that my beliefs are similar and I haven't gone off the deep end.
So my advise, is to do a little research. If you hold no religious beliefs, it may be difficult. But your husband needs to know that truth still exists, but not in the Watchtower. A person does not need atheism or agnosticism. What they need are choices. Unfortunately, this site does not always clearly show those options. This does not help those who are "jolted awake" like I was. This is one of many choices. I hope things work out for you.
