Glenn, thanks so much for sharing your personal story and testimony with me. I am very glad that that it has helped you in your life. I wish you only the best.
For the purposes of this topic I will describe a few types of Spirit experiences:
1) You intellectually see a clear path and the Spirit confirms it with good feelings
2) You have good feelings about a choice and attribute them to the Spirit
3) You have good feelings about a thing (like a belief or a church) and attribute it to the Spirit
4) You have good feelings about a person and attribute them to the Spirit l
I have done all four of these things and more, as I guess you surely also have. There are also other ways to describe the Spirit. Yet, my evaluation about the Spirit has changed and I no longer believe experiences like 2, 3, or 4 are necessarily valid examples of the Spirit of God. They imo can be overgeneralised to legitimize too much.
For example, many Spirit experiences can be very simple witnesses of the worth of a person, be it yourself or others and are common as we make choices validating that worth.
Moroni's Promise, rather than a real truth-seeking method, now seems to me like an emotional method to leverage loyalty to the Book of Mormon. There are so many things in the book which can generate strong feelings to facilitate this method.
Alternatively, I think the Spirit will testify of things more simply and specifically, one thing at a time. To me, a church with a claim of authority and direct line to God is an inadequate replacement of the authentic spiritual life. While an authentic spiritusl life might happen concurrently as one participates in a "one true church," I think that at some point or points the two will likely diverge.
Sometimes the separation becomes untenable.
I guess it really comes down to blind faith. To me, one cannot prioritise another person's spiritual experience over one's own.
If one, then, is going to be an active participant of equal worth in a spiritual gathering of believers, they will see the doings common to their group, that those experiences can be made opportunities to feel the Spirit with an informed mind, more expansively and more authentically. These doings, whatever they are, will be continually an inseparable part of the shared experieces. Hiding such things is only a hindrance to growth and unity.
