The Heart of the Mind
One big reason, even intelligent people dont know the deeper truths of the gospel, like Cosmism is that they mistake emotion for the spirit. How can you know these deeper truths?
Not the Heart
When something feels (emotionally) good, too many of us automatically think its from the spirit. Be very careful when you "know" something to be true because the spirit confirmed to your heart it was true. If it cannot also be confirmed through your mind, you don't have a confirmation. Emotions deceive far too often. An emotional confirmation can too easily be evil, as it is deceptive. It is easy for any of us to love something that we know is at some level, destructive.
But the mind
If it's not confirmed in your mind and gets your intelligence "buzzing" and is virtuous, lovely, and of good report or praiseworthy, then it is not a confirmation. It is most likely just a good emotional feeling, and nothing more. God speaks thoughts to your mind, and feelings to your heart. Only after you have tried your hardest through reading, researching, and studying to find the answer yourself, does the spirit confirm it in the "heart" of your mind.
"Verily, verily, I say unto you, if you desire a further witness, cast your mind upon the night that you cried unto me in your heart, that you might know concerning the truth of these things. Did I not speak peace to your mind concerning the matter? What greater witness can you have than from God?"
How do you speak an emotion to a mind? You dont.
"Yea, behold, I will tell you in your mind and in your heart, by the Holy Ghost, which shall come upon you and which shall dwell in your heart. Now, behold, this is the spirit of revelation; behold, this is the spirit by which Moses brought the children of Israel through the Red Sea on dry ground."
The "feel-good" churches
Most churches, including the LDS church backs these feelings up and supports them 100%. In general, the larger part of most of these churchs have become "feel good" churches. Instead of being a church of true revelation, prophecy, and confirmation by the spirit, they have been decieved into believing that all things important come through your emotions. This is pretty scary if you think about it. Any church that supports this idea is wrong to lead people to believe in this emotional guidance, and is in fact leading people astray on their teachings of this very important principle.
We in this church have become sheeple, waiting on the hierarchy to tell us what is important, condemning us for being compelled in all things. Be self-reliant, especially spiritually.
I don't mean to disrespect any church in general, but I do intend to call them out on the doctrines they teach falsely.
Emotionalism
So many of the Christian sects are based on charismatic fervor and emotionalism. The congregation is moved by a slick talking used car salesman that thumps the Bible and whips them up into a frenzy prior to passing the collection plate. The same can be said with a slow talking but emotional "mover".
Personal revelation is something entirely different. God speaks in a spiritual voice that can't be defined in temporal terms. It seems like its at a level that by-passes the filters of ego and natural senses, yet experienced in your heart and understood in your mind. You just know. No arguing with the Holy Spirit.
Spiritual vs Corporeal
Most church members think that everything in life has to be on a spiritual or religious level, otherwise its just not worth any time or effort. Cosmism, which is the temporal and scientific half of the gospel, and equally as important, is quickly rejected by most when they first encounter it. Their cognitive dissonance kicks in. Most people usually choose emotionalism, over scientific, logical topics.
The Mind will protect false beliefs
Cognitive Dissonence: the state of having inconsistent thoughts, beliefs, or attitudes, especially as relating to behavioural decisions and attitude change. In the field of psychology, cognitive dissonance is the mental discomfort experienced by a person who simultaneously holds two or more contradictory beliefs, ideas, or values.
“Sometimes people hold a core belief that is very strong. When they are presented with evidence that works against that belief, the new evidence cannot be accepted. It would create a feeling that is extremely uncomfortable, called cognitive dissonance. And because it is so important to protect the core belief, they will rationalize, ignore and even deny anything that doesn't fit in with the core belief.”
This is what happens when Cosmism is presented to most people.
Where is the heart according to scripture?
According to the scriptures, the heart is the seat of thought and reason, and not the brain. In other words, thought and reason is where God speaks to a person, not the physical/emotional blood-pumping heart. It is a place where words are spoken and thoughts and ideas pondered and reasoned out. It is the center of reason. It is where thoughts are placed and spoken. It is where words are stored, remembered, or treasured.
The Heart spoken of in the scriptures means "center" (deepest central part) of the mind.
"Then Abraham fell upon his face... and said in his heart"
"Hearken ye to these words... Treasure these things in your hearts."
"Behold, I would exhort you that when ye shall read these things... (ye shall) ponder it in your hearts."
“But when Jesus perceived their thoughts, he answering said unto them, What reason ye in your hearts?”
The ancient "Heart"
"Kardia", used in the New Testament, is the Greek term for "Heart".
Kardia = heart, mind, character, inner self, intention, will, or center.
The ancients, including the philosopher Aristotle, as well as the Egyptians thought the heart, not the brain, was the location of intelligence and the seat of thought.
The modern "Heart"
When we read this in section 8 of the Doctrine & Covenant, we see no sign of emotions. The heart when considered within the larger scriptural and historical context is the perfect place to tell somone something.
"Yea, behold, I will tell you in your mind and in your heart, by the Holy Ghost, which shall come upon you and which shall dwell in your heart. Now, behold, this is the spirit of revelation; behold, this is the spirit by which Moses brought the children of Israel through the Red Sea on dry ground."
Strive for Spiritual Confirmation
Ask, Seek, Knock: Spend the time and effort to Read-Study-Research the material and put the pieces together to build a full picture.
Have Faith: Plant the seeds of Faith on a subject or theory, line upon line, then help it grow into a perfect knowledge of truth of that subject through your research and works. Dont just keep believeing, Test it. Prove it. Know.
Intelligence: Get a confirmation through the spirit that will come through your mind, not your emotions. Feeling God'd love is the only confirmation I can think of to recieve through your emotions. All else is false doctrine.
