I can tell talking to old friends that they don’t really believe in JW theology, well not convinced of it. But it would be nice if it’s true and there is a possibility of that of parts of it at least.
JW theology is designed like a "take away" or "to go" fast food. Even if you leave the org because of disillusionment with date setting, most keep the theology that appeals to the sin nature:
1. When you die, you are anihliated. No chance of being conscious forever.
2. 2nd Chance Theology. You get to pay for your sins yourself when you die and be resurrected in paradise for a do-over.
This is the theological hope of most JW's after they leave. It is very comfortable and doesn't require any commitment to an organization. It's a sort of parting gift, compliments of the WT.
Jesus says its a lie though.
