Enos is a special book. Small in size, it is long on principles, the most important one being repentance. I love the question Enos asks after he is told that his sins are forgiven. I believe he wants to know how the guilt was removed since his relief is so real. The release of guilt comes with faith in Christ. Then Enos is told to move forward, act on the new impetus to do good, which Enos does by opening his heart to others.
The records, most valued and prized, are passed through four families, Lehi, Benjamin, Alma, and Mormon. We live in a time when scriptures are easily accessible, but it has not been so in the history of the earth.
Omni is a record with many hints of events to come. It took me years to realize that reading this small account was vital to understanding the plot of the book of Mosiah.
