A couple of thoughts:is it always God's goal for an individual to continue in the LDS faith? What if trying to stay hurts a person's spirituality more than going somewhere else for spirituality?
- I don't think God has goals. People sometimes conflate God with man or earth with eternity. If you believe in LDS scripture, he refers to his "work" and "his glory" being to bring to pass the immortality and eternal life of man. Those are spiritual goals, not religious ones. Religious goals are things like church attendance, how much tithing is paid, temple recommend holders, etc. Spiritual goals are things humans can neither see nor measure - the yardstick of our souls against our potential.
- There are probably some for whom staying LDS is more damaging than leaving. I absolutely believe that is the case. The environment may be toxic for some, or they may be toxic to Mormonism. Perhaps they need to get out before they can deal with it. Or maybe they can never deal with it. Personally, I think there is a real risk to get stuck in Stage 4 in leaving. I think it's more powerful to get over stuff and to find one's own reserves. There is more spiritual power in working through stuff than in not working through stuff. It's possible to work through things and leave, but what you are leaving (the stuff that bugs you) is not really part of you anyway. Disaffection is making it more important than it is.
- Religions are not the source of spirituality. They only help (or don't help) you tap into your own spiritual reserves, to help you achieve your human potential, to help you get closer to God. Humans are inherently spiritual. Religions are human organizations to achieve those aims, presumably with inspiration as well, but every religion has flaws. Trying to find one without flaws is to find one with no people in it at all.
