Nephi knew Christ had redeemed his soul from hell, for He had declared it to Nephi. The reason Nephi understood the fullness of Christ's Gospel, could declare the doctrine of Christ, and was a prophet given a commission to teach was because he had been taught by the Lord. (2 Nephi 11: 2.) The return to Christ's presence was not merely a spectacular event to write in a journal, or a bragging point to claim among others. Indeed, much of what Nephi obtained from the Lord was never recorded for us or Nephi's posterity. The return was to obtain light and truth, or intelligence, which is the glory of God. It was to be ministered to by the Perfect Teacher. This, in turn, made Nephi the great minister he became.
Nephi may have gloried in plainness, but we glory in positive messages telling us we will be saved in our sins. Nephi may have gloried in Jesus, but we use His name to endorse our products and ratify our false teachings. Nephi may have urged the plainness of truth itself, but we market based on focus group tested and opinion polled results so our product line should get good market acceptance.
