I love this crunchy-leaf time of year. 

Reading this part of the Book of Mormon  is a strange contrast – Mormon Chapter 6 saw over 230,000 people killed in battle, but Mormon turns and writes such a message of hope for us in chapter 7. He witnesses his nation self-destruct. His heart had to have been shattered into 230,000 pieces. So what does he do? He writes to testify to his far-distant progeny, or the progeny of his enemies, if anyone should escape and survive the war, “Repent and believe in Jesus.” 
It’s amazing to me. He’s not shouting, “God where are you in all this carnage?” He’s saying, “God’s with those who look for him. Repent and find life in him.” 

Mormon 7: 

“5 Know ye that ye must come to the knowledge of your fathers, and repent of all your sins and iniquities, and believe in Jesus Christ, that he is the Son of God, and that he was slain by the Jews, and by the power of the Father he hath risen again, whereby he hath gained the victory over the grave; and also in him is the sting of death swallowed up.”
