1 Nephi 17:45

Nephi continues his verbal assessment of the spirituality of Laman and Lemuel. In verse 45, he says that they are swift to do iniquity and slow to remember the Lord their God. He reminds them that they have seen an angel and that since then they have heard his words from time to time.

I did a quick search of the word "angel" in the Book of Mormon up to this point (i.e., 1 Nephi 1-17). In chapter 1, Lehi sees a vision of angels praising God. In chapter 3, we find the first time the angel appears to Lehi's sons and stops Laman and Lemuel from smiting their younger brothers with a rod and commands them to go back to Jerusalem and Laban would be delivered unto them. In chapter 4, just after they saw the angel, Laman and Lemuel still do not believe that they could get the plates, even if the guardian of those plates would be delivered unto them. They believe that he would still be able to slay 50 people. In chapter 7, Laman and Lemuel are returning from Jerusalem with Ishmael and his family, and they along with some of Ishmael's family do not want to follow the commandment of the Lord to flee Jerusalem to avoid destruction. Nephi is grieved because they had seen an angel and he told them that they must get the plates for their jouney. In chapters 11-15, Nephi receives a vision where an angel shows and teaches him all things. In chapter 16, Laman and Lemuel accuse Nephi of pretending that angels minister unto him. This is odd because angels have ministered unto them, but they treat it as if it were a lie. Even though it happened to them they do not believe it and forget about it. This could also add meaning to the phrase "past feeling" which is what has to do with angels and Laman and Lemuel in chapter 17.

He tells them that he has spoken in a still, small voice and that they could not feel his words because they were past feeling. And so, if the angel needed to convey a message, he has to use a voice of thunder insomuch that the earth would shake and threaten to split into two.

Let us not forget our spiritual experiences and later deny them as Laman and Lemuel. Let us use them as motivators for doing what it right and helping others do so as well. One way to do this is to record these experiences in a personal spiritual journal.
