Mosiah 20:11

"And it came to pass that the people of Limhi began to drive the Lamanites before them; yet they were not half so numerous as the Lamanites. But they fought for their lives, and for their wives, and for their children; therefore they exerted themselves and like dragons did they fight."

Even though the people of Limhi were completely out-numbered in battle they conquered.  They were able to do so well because they had good reasons to fight.  They were protecting their families.  Today there is a huge battle against the family.  Just like these people, we should fight for the sanctity of the family. Families are worth it and must be protected!
