n Genesis 15 Abraham begins losing faith that his promise from the Lord would be fulfilled. Sarah in her old age had not born him a son which would allow innumerable posterity. We can learn a great lesson from Abraham, Lehi and Nephi as they have all had similar experiences as this account.
One reason why being able to recognize our promptings that have come from the spirit and to know that God has spoken to us directly about our daily lives- is because we all have times when we will need to be able to recall and hold close these sacred experiences that we have in our hearts and journals; in order that we can endure our trials.

Perhaps Lehi's vision of the Tree of Life was a great tender mercy that he could hold onto while thrashing in the sea with his rebellious children Laman and Lemuel as they were punished by the storm?
