1 Nephi 22:30

"Wherefore, my brethren, I would that ye should consider that the things which have been written upon the plates of brass are true; and they testify that a man must be obedient to the commandments of God."

The Book of Mormon is true.  It is a good book, and if I follow the teachings within it I will be blessed. This book teaches that we all must keep the commandments of God. There is no other way to be truly happy.  I know that my life has been greatly blessed because I live in accordance to these commandments.
