From the Book of Mormon we learn how disciples of Christ live in times of war.
A man must not only stand for the right principles, but he must also fight for them. Those who fight for principle can be proud of the friends they've gained and the enemies they've earned.
Be right, and then be easy to live with, if possible, but in that order.
It is better to prepare and prevent than it is to repair and repent.
With pride, there are many curses. With humility, there come many blessings.
The Book of Mormon is the "keystone" of our religion, and the Doctrine and Covenants is the capstone, with continuing latter-day revelation.
