Learning Navi on a deeper level explains to us the inner workings of our own yetzer hara. The battles that the Neviim had to fight were to teach us how to fight off our personal battles. On a very surface level, here is an example; There are specific cycles that reoccur in Navi where the Klal behaves, then they begin to sin, then Hashem sends an enemy to attack, then Bnei Yisroel suffer, Hashem sends the Navi to help them fight, they succeed in battle. Cycle reoccurs. Each battles represents a stage in life and specific challenges that people face.
Learning Navi is most appropriate for all Jewish people but I can understand that it can be boring if you are reading like history without synthesizing the
information into your personal life. I can assure you that if you learn Navi with the deeper meanings-you will consider it your best class!
ps There were many incidents that were not recorded in Navi because they were not relevant to guide us.
