The Book of Mormon wrestles with the tension between aspiring to peace but being faced with the reality of a fallen world.
I believe the Book of Mormon was specifically written for the modern world. We all need it's profound message to come unto Christ.
We live for Christ not in order to someday gain His acceptance. We live for Christ because we already have it.
In Mormonism, covenants anchor us to Christ and set us free to live our faith rather than chain us to dogmatism.
