Eight of the 39 books in the Old Testament were definitely in the brass plates, and another 16 may have been included. For Book of Mormon prophets, the brass plates were an essential part of their identity: connecting them to intergenerational covenants, testifying of the Savior, and bringing them closer to God.
Springing Up
The tree of life in Lehi's dream also functions as a fountain of living water. Alma said that the tree of life can grow in our hearts. Jesus promised a well of living water in the hearts of those who follow Him. Both the tree and the fountain "spring up," lifting us closer to God.
Moroni’s Collaborative Conclusion
Moroni draws heavily on the writings of his precessors in his concluding remarks. This collaboration with prior prophets enhances the power of his message and helps us to see "how merciful the Lord hath been." in all ages of the world.
“O God…”
The expression "O God" is characteristic of the Old Testament, and particularly the book of Psalms. The few times it appears in the Book of Mormon, it conveys a special earnestness. So, it's fitting that the sacrament prayers would begin with those words.
Searching
We normally "search" for something in particular. But the Savior's instruction to "search the prophets," may have a more general meaning. We may benefit from simply asking what the prophets were trying to say and what their messages mean for us.
Wilderness, Field, House, and Closet
Zenos listed four places where God had heard him. Amulek specifically connected the last one, closets, with the first, wildernesses. We need to share the most uncomfortable parts of our lives with God in order to learn from Him and receive His grace.
Ask Not Amiss
Jesus promised that our prayers will be answered. James added a caution: we need to pray with the right motives. Bishop Keith B. McMullin taught that the Spirit can help us understand what to ask for, so that our prayers can be aligned with God's will.
Praying Always
What does praying always look like in your life? For me, it means that I have a prayer in my heart throughout the day. It also means pausing to pray before a daunting task. God is always available to hear us, and we should frequently talk with Him.
“All Things”
Jesus promised that the Holy Ghost would teach us all things. Nephi and Moroni taught the same. What does that mean? 1. He is omniscient. 2. He can lead us to the next bit of knowledge we need. 3. He can help us in all aspects of our lives on any subject.
“In Spirit and in Truth”
Sacred times and places are important, and we benefit from treating them with reverence. But as Jesus taught the Samaritan woman, and as Alma and Amulek taught the Zoramites, the ultimate goal is communion with God.
