Many times in the Book of Mormon, the authors say that God has commanded them to write their book for a wise purpose, which only God knows. And yet, other times in the book they seem to know exactly what the purpose is, that is, to convert future generations to God and that they can know of the covenants that God has made with Israel.
Mormon, for example, in Words of Mormon verse 7-8 says,
7 And I do this for a wise purpose; for thus it whispereth me, according to the workings of the Spirit of the Lord which is in me. And now, I do not know all things; but the Lord knoweth all things which are to come; wherefore, he worketh in me to do according to his will.
8 And my prayer to God is concerning my brethren, that they may once again come to the knowledge of God, yea, the redemption of Christ; that they may once again be a delightsome people.
It’s as if he hopes that the purpose is to restore the Lamanites, but he isn’t sure enough to declare what God has in mind.
But then Mormon himself says, in 3 Nephi 5: 14-15,
14 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 according to their faith, should make a record of these things which have been done—
15 Yea, a small record of that which hath taken place from the time that Lehi left Jerusalem, even down until the present time.
And there are several places in the book where it’s laid out clearly that the prophets, or the fathers, had asked God to preserve their record and send it to the Lamanites when the time was right (see, for example, Enos verses 16-18). And it seems that Mormon is very aware of these verses, or at least of this promise.
So why the confusion? Why is Mormon unsure of the wise purpose that God has? Why is Nephi sometimes unsure? Is it simply that they know there might be other reasons? Has God communicated to them that there are other reasons? But then also, Nephi and Mormon seem to hope that the purpose is to restore their brothers. So sometimes it seems like they aren’t sure that that actually is a purpose, or something they just desperately hope will be a purpose.
So I remain a bit confused.
