According to John Tvedtnes, one of the clearest and most precise definitions of faith is the one given in the Book of Mormon by Alma: "If ye have faith ye hope for things which are not seen, which are true" (Alma 32:21). To gain a full appreciation of this definition, we must understand that the Hebrew words for faith and truth are related, both coming from the root *MN. Hebrew emunah means "belief" or "faith," while emet means "truth." Both are related to yamin, "right hand," and to amen, "established," the word with which prayers are ended.
Joseph Smith is said to have indicated that the name Ahman was the title of God the Father (see 2 Nephi 4:35), while Jesus is called "Son Ahman." Old Testament prayers end simply with the word Amen (= confirmed, true), and hence in the name (title) of Jesus Christ.
In Mosiah 27:36, the knowledge of the truth is equated with the knowledge of Christ. Mormon writes concerning the missionary efforts of Alma the Younger and the four sons of Mosiah: "And thus they were instruments in the hands of God in bringing many to the knowledge of the truth, yea, to the knowledge of their Redeemer."
