According to Hugh Nibley, in Mosiah 4:5 during king Benjamin's sermon, when the people are in the height of their glory, Benjamin starts reminding them of their worthlessness and their nothingness in the worthless and fallen state. I don't think that would offend them at all. If you were in the presence of celestial glory, you would certainly feel that way and you wouldn't feel at all insulted. They don't feel like crawling under rocks though. They feel pretty good about it. Benjamin says, You have come to a knowledge of the goodness of God; you see how good he can be now. This is the grace of God. This is "the atonement which has been prepared from the foundation of the world, that thereby salvation might come to him that should put his trust in the Lord, and should be diligent in keeping his commandments, and continue in the faith even unto the end of his life . . . " (Mosiah 4:6). The reader should note that the phrase, "the atonement which has been prepared from the foundation of the world" is a biblical expression, too, although Christians ignore that. [Hugh W. Nibley, Teachings of the Book of Mormon, Semester 1, p. 471]
Note* For the benefit of the reader, a few of these biblical references are as follows:
". . . I will utter things which have been kept secret from the foundation of the world." (Matthew 13:35)
"Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world." (John 17:24)
"But with the precious blood of Christ, as of a lamb without blemish and without spot: Who verily was foreordained before the foundation of the world, but was manifest in these last times for you, . . . (1 Peter 1:19-20)
"And all that dwell upon the earth shall worship him [Satan], whose names are not written in the book of life of the Lamb slain from the foundation of the world." (Revelation 13:8)

“Prepared from the Foundation of the World”
John Tvedtnes and Matthew Roper write that in a recent Ensign article and in his talk at the April 2000 General Conference, Elder Russell M. Nelson of the Quorum of the Twelve Apostles cited a passage from a fourth-century-A.D. document known as Discourse on Abbaton. Written by Timothy, archbishop of Alexandria, Egypt (d. 385), the text contains a passage in which Christ says of his Father the following:
He . . . made Adam according to Our image and likeness, and he left him lying for forty days and forty nights without putting breath into him. And He heaved sighs over him, saying, "If I put breath into this [man], he must suffer many pains." And I said unto My Father," Put breath into him; I will be an advocate for him." And My Father said unto Me, "If I put breath into him, My beloved Son, Thou wilt be obliged to go down into the world, and to suffer many pains for him before Thou shalt have redeemed him, and made him to come back to his primal state." And I said unto My Father, "Put breath into him; I will be his advocate, and I will go down into the world, and will fulfil Thy command."
The Book of Mormon repeatedly informs us that the atonement of Christ was "prepared from the foundation of the world" (Mosiah 4:6-7; 15:19; 18:13; Alma 12:30; 18:39; 22:13; 42:26; see 1 Peter 1:20; Revelation 13:8). When the premortal Lord appeared to the brother of Jared, He declared: "Behold, I am he who was prepared from the foundation of the world to redeem my people. Behold, I am Jesus Christ" (Ether 3:14).
In number of early Christian texts the premortal Christ himself tells Adam and Eve of his future redemption of mankind. Among these texts are the Armenian Expulsion of Adam and Eve from the Gardenand the Ethiopic Conflict of Adam and Eve I. In still other passages, it is the Father who tells Adam of the forthcoming atonement of Christ. These include the Arabic Book of the Rolls, folios 96a, 100b; and the Syriac Cave of Treasure, folio 7b, columns 1-2. A number of stories also have angels coming to deliver the same message to Adam. Among these are several Armenian texts; Adam, Eve and the Incarnation 39-43; Adam Story I; History of Abel and Cain the Sons of Adam; and the 10th Century Byzantine scholar George Cedrenius's Historiarum Compendium, 1:17.
From these examples we can see that early Christians in such disparate locations as Armenia, Syria, Egypt, and Ethiopia believed not only that Christ had been designated as Savior prior to Adam's creation, but also that Adam and his immediate posterity were fully aware of God's plan of redemption.
