The fullness of the Gospel is found in the Book of Mormon. There you will find individual after individual who have returned, through faith, back to God's presence. Once they have returned to God's presence, they have a different view of themselves and others.
In the case of Lehi and his family, he listened to the testimony of others warning of the destruction of Jerusalem, took their warning seriously, and begged God on behalf of his people. (1 Ne. 1: 5.) As a result of his intercession and compassion for others, he was visited by God. (1 Ne. 1: 6.)
Lehi's family did not believe him. They followed him into the wilderness, but only because of the respect accorded to the father in their society. None of the family could believe what he was saying.
The younger son, Nephi, prayed to be able to believe what his father Lehi was saying. Even though Nephi wanted to acquire faith, it was not easy to trust his father's message. Because of his desire to believe, Nephi reports the Lord "did visit me;" this sounds like something more than it was. The Lord's initial "visit" to Nephi consisted only in 'softening Nephi's heart so that he was able to believe his father.' (1 Ne. 2: 16.)
This is the beginning. This is the first step. When the Lord first takes hold of your hand, it is a faint grip, a partial contact, a weak beginning. It is the token, however, that everyone must first receive. It comes from obeying and then acting faithfully on what has been shown to you. It requires you to sacrifice your own will to the Lord's.
No one will return to the presence of God who has not received this gentle grip from the Lord. It is a true token given by the Lord; not just something ceremonial. It is the companion to faith. It is the start of the path you will walk back to the presence of God, passing the sentinels who stand along the way. They will want to know you have learned all you need from your experiences here to be able to return to God's presence.
When the most dramatic points of struggle happen along the path, the Book of Mormon provides us with a view into the person where the struggle takes place. Nephi's record of the fullness includes his testimony of kneeling on a dark Jerusalem street where he found the person of Laban lying drunk and unconscious before him. (1 Ne. 4: 7-8.) He disarmed him. Then took the time to admire the weapon of war he had taken from his fallen uncle, noting its precious material and workmanship. (1 Ne. 4: 9.)
While admiring the sword, he had the urge to slay Laban. (1 Ne. 4: 10.) Though Nephi attributed this impulse to "the Spirit" it was nothing more than an impulse. Here is where the cosmic struggle plays out. In Nephi's heart, there is a strong urge to kill a man which, in Nephi's life, is unprecedented. It is foreign to him. It is "the Spirit" and not Nephi who has this will to kill the man.
Nephi's hesitancy is not based solely on moral scruples, but on all he believes about himself. He is not a man of war. He has "never before shed the blood of man" and does not think it appropriate to start now. (1 Ne. 4: 10.) This is not about self control, this is about who his identity. This is who Nephi believes himself to be. He is better than this base impulse. It is beneath him.
When he resists this impulse, "the Spirit" elevates the message. No longer is it "constraint" or inclination, but "the Spirit" now "speaks" to him in unmistakable words. (1 Ne. 4: 11.) The message not only clearly tells Nephi the Lord's will in 'delivering Laban into his hands,' but also makes enough sense to Nephi that he can immediately recognize the many reasons for the Lord accomplishing this. (1 Ne. 4: 11.) The proof of the Lord's hand lays before Nephi. After all, Laban is lying helpless, and "has been delivered into thy hands" as the most tangible, clear proof of God's power. (Id.)
Yet all of this struggle is internal to Nephi. You could stand on the same street, at the same moment and see the same scene play out before you, and you would not be a witness to God's great work underway.
The fullness of the Gospel requires us to recognize the hand of God guiding us. The battle we join is within. No one is spared from these stages of growth and development.
The church cannot provide you with an alternative means to get there. It is between you and God, alone. The scene will be as the Book of Mormon continually portrays it. That record is the most comprehensive retelling of how to return to God's presence ever compiled. It was put together by those who made the journey along the path, passing all the sentinels who stand guard along the way. They embraced their Lord through the veil before entering again into His presence. Then, having been true and faithful, they were brought back into His presence and redeemed from the fall of mankind. (Ether 3: 13.) They, like the Brother of Jared, were redeemed because of their knowledge. (Ether 3: 19.)
Yet you insist on captivity because you have no knowledge. (Isa. 5: 13.) You take blind guides and are therefore, blinded by your own ignorance. (Matt. 23: 16.) You insist on keeping what can never inform you, while rejecting what is told you in plain words. (2 Ne. 32: 7.) You refuse to see and are willingly blind and therefore the greater darkness lies within you.
You can wait until there is a program offered to you by an institution and see how long it takes for you to learn of God. Or, believe in the Book of Mormon and remove yourself from condemnation. (D&C 84: 56-57.) But if you seek for approval from an institution, then the Lord cannot overcome the barrier you have erected between you and Him.
