Mormon 7

Interesting enough, what I find very loving, compassionate, and of charity that he preached so much of, is that Mormon chooses to conclude his final words is to the enemies of which he had fought against most of his life saying -

"AND now, behold, I would speak somewhat unto the remnant of this people who are spared, if it so be that God may give unto them my words, that they may know of the things of their fathers; yea, I speak unto you, ye remnant of the house of Israel; and these are the words which I speak..."  (Book of Mormon | Mormon 7:1)

He proceeds to testify of Christ, His gospel, and they can be saved.  What great charity!
