"Continually running into the fountain of all righteousness"

"And when my father saw that the waters of the river emptied into the fountain of the Red Sea, he spake unto Laman, saying: O that thou mightest be like unto this river, continually running into the fountain of all righteousness! 10 And he also spake unto Lemuel: O that thou mightest be like unto this valley, firm and steadfast, and immovable in keeping the commandments of the Lord!"

I like the idea of "running" into righteousness. It seems to imply speed or urgency, and consistency.

Obedience

"And it came to pass that he was obedient unto the word of the Lord, wherefore he did as the Lord commanded him."  Obedience means that we actually do what God has asked us to do!

1 Nephi 1:20

"But behold, I, Nephi, will show unto you that the tender mercies of the Lord are over all those whom he hath chosen, because of their faith, to make them mighty even unto the power of deliverance."

Book of Mormon Daily: Coming to know the Creator; 1 Nephi 2:12-17

"And [Laman and Lemuel] did murmur because they knew not the dealings of that God who had created them," (1 Nephi 2:12, Book of Mormon).

Judging from the evidence in the text, we learn a few things about Lehi:

1. Because of the words of the prophets of his time Lehi cried to God for his people (see 1 Nephi 1:4-5). 
2. The result of Lehi's pleading to God was his reception of a vision, where, the record indicates, "he saw and heard much," (1 Nephi 1:6). 
3. Lehi learned how to communicate with God. He learned and felt compelled to share important truths that God taught him!
4. Lehi often taught these truths to his children.
5. Lehi possessed the spirit of prophecy.

Laman and Lemuel's younger brother, Nephi, observed that the reason his older brothers complained was because, "they knew not the dealings of that God who had created them,"  (1 Nephi 2:12, Book of Mormon). So, the question, why didn't they know the dealings of the God who had created them? In the text, it is clear that Nephi does know the dealings of the Creator. And, the text also gives us clues about how Nephi came to know the Creator:

1. As far as I can tell, the two major differences between Nephi and Laman and Lemuel are that Nephi desired to know God's mysteries, and, motivated by this desire, he "did cry unto the Lord," in sincere, heartfelt prayer, while Laman and Lemuel did not. Could it really be that simple? In 1 Nephi 2:16, Nephi states, 
1. "And it came to pass that I, Nephi, being exceedingly young, nevertheless being large in stature, and also having great desires to know of the mysteries of God, wherefore, I did cry unto the Lord; and behold he did visit me, and did soften my heart that I did believe all the words which had been spoken by my father;
2. Because Nephi had a deep desire to know God's mysteries, and because Nephi expressed this sincere desire in faith through prayer, God visited him and softened his heart! The text indicates that this softening is the reason that Nephi believed the words of his father. 

How do we come to know the "dealings of that God who created [us]"? What did Lehi and Nephi do?

1. Lehi acted on the words of the prophets of is day. The text says, "there came many prophets prophesying unto the people that they must repent, or the great city Jerusalem must be destroyed. Wherefore . . ." (1 Nephi 1:4-5, emphasis added). To me, this word, "wherefore," indicates that because of the words of the prophets, Lehi did what he did in verse 5 (that is, "he . . . prayed unto the Lord, yea even with all his heart, in behalf of his people"). Because of what the prophets did and said, Lehi acted.
2. Lehi was motivated by the testimony of prophets. As he acted on the prophets' words, he himself had his own miraculous visionary experience. He saw a pillar of fire (incidentally very consistent with other visions and manifestations of God; when the Israelites were freed from Bondage in Egypt, God went before them in a cloud by day and in a pillar of fire by night; Joseph Smith begins his 1838 description of his vision of God the Father and His Son Jesus Christ with the words, "I saw a pillar of light. . ." (Joseph Smith history 1:17, emphasis added); in the Book of Ether in the Book of Mormon, Jehovah went before the Jaredites in a cloud in a similar manner as he did the Israelites who were being freed from Egypt).  

1 Nephi 2:7

"And it came to pass that he built an altar of stones, and made an offering unto the Lord, and gave thanks unto the Lord our God."
Lehi was grateful, even though he had to flee for his life. He still remembered God in gratitude.
