Understandably, in your state of significantly diminished faith, you are confusing the "Holy Ghost" (the means by which we may know the truth of ALL THINGS) with "asking God in prayer". The Holy Ghost works in various ways, whether ostensively through direct answers to prayers (Moroni 10), or experiencially when people comply with the principles and ordinaces and commandments of the gospel (Alma 32).
For heaven’s sake, Wade. Moroni’s promise is clearly about asking God directly in prayer. That is the context in which the HG conveys the truth of all things.
4 And when ye shall receive these things, I would exhort you that ye would ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, with real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost.
5 And by the power of the Holy Ghost ye may know the truth of all things.
I’m not contesting that Alma gives another path to know truth. I am contesting your unnatural insistence to limit the process described in Moroni to the BEGINNING.
In fact, the talk I quoted from Elder Cook directly contradicts this assertion of yours.
Thus, while a first-time reader and ponderer may receive the needed confirmation of the book’s divine origin, members who long ago passed that milestone may have other new truths added to their spiritual store as they search the scriptures and follow the process described in Moroni 10:3–5 [Moro. 10:3–5]. The promise is extended to confirming “the truth of all things” (emphasis added); there is no restriction on the amount of truth we may receive through this process.
This fallaciously assumes that people will invariably draw the same rational conclusion and not change their minds about the conclusion. Your own personal story negates that fallacious assumption.
Then clearly there is not irrefutable tactic connection between the two.
I don't doubt in the least your sincerity. What I question is whether you correctly understood the process of growth, and correctly used the process of growth. I believe you were mistaken on both accounts, and as such failed to recognize the Alma 32 confirmations from God. Again, it isn't revelation that is unreliable, but people unreliably using it. Those who actually correctly get the nature of revelation, and who have properly used it in their growth in faith, find it to be quite reliable.
It doesn’t matter on which side the unreliability occurs. If human beings are too flawed to use revelation in a reliable manner, than revelation is an unreliable method of communication.
