Mormon writes:

"And it hath become expedient that I, according to the will of God, that the prayers of those who have gone hence, who were the holy ones, should be fulfilled acccording to their faith, should make a record of these things which have been done - Yea, a small record of that which hath taken place from the time that Lehi left Jerusalem, even down until the present time. Therefore I do make my record from the accounts which have been given by those who were before me, until the commencement of my day; And then I do make a record of the things which I have seen with mine own eyes. And I know the record which I make to be a just and a true record; nevertheless there are many things which, according to our language, we are not able to write."
3 Nephi 5:14-18.

I know that the Book of Mormon is true and I'm thankful for it.

A favorite scripture of mine is:

"And what is it that ye shall hope for? Behold I say unto you that ye shall have hope through the atonement of Christ and the power of his resurrection, to be raised unto life eternal, and this because of your faith in him according to the promise."
Moroni 7:41.
