You lost me here. How does one's feeling of certainty show that is was from the HG?
Are you suggesting that someone who has an experience generated only by their body of an answer to coming into their mind will not be able to have no doubts about it?
Also, if we assume the HG exists and does give revelation to people, are you suggesting if the HG sends a message to a person they cannot doubt it or where they think the experience is coming from? Can we find examples of church leaders doubting some of the spiritual experiences they believe are from the HG?
Communication is always so difficult for me.
The feeling of certainty does not guarantee the source, but if you receive something from the Holy Ghost it will be accompanied with the feeling of certainty. But that is only one of the identifiers. There are many elements that make up the "signature" of the Holy Ghost. All of them will be present if and when you are given a message by the source of the Holy Ghost. If any of them are missing, then the only thing you can be sure of is that it is not from the Holy Ghost. This is where an experience generated by the body or some other outside source comes in. Granted those experiences can feel very significant, but that is all the more reason to being able to recognize the source. Without the certainty that comes with the Holy Ghost, we are confused and misled at best.
Like I said before, it is like recognizing the voice of your spouse. Tell me how that happens? How do you go from not knowing their voice at all to being able to recognize and sort it out even in a crowd of 100 people talking all at once? Most people wouldn't consider it important to recognize my wife's voice, but it is very important to me. Does it impact the importance of her voice in my life if 99.999% of the world's population doesn't recognize it? Not at all. Is it any less recognizable to me just because you don't recognize it?
Even when a message is delivered powerfly such as a physical appearance of an angel, a message can be doubted. Look at the experiences of the brothers of Nephi. Even with their physical experiences they were able to doubt and falter. God does not compel us to believe or even comply with his instruction.
How much easier is it for us to doubt when we receive instuction via a still small voice? I think that many times our lack of faith, our doubting, prevents us from being taught in this manner. In many ways, the experience of the Holy Ghost is reserved for only those who have prepared themselves to receive it. The rest of us have to learn by the school of hard knocks. That seems to be status of most in this world.
It is apparent that few people have prepared themselves sufficently to enjoy that priviledge. This is really a sad state of affairs that so many people with the benefits of the teachings of Joseph Smith have learned so little of what is really important. Joseph taught that without being able to recognize the Holy Ghost that we would never have power unto salvation. So where does that leave the vast majority of those that expect to be exalted?
