‘Faith is essential for healing by the powers of heaven. The Book of Mormon even teaches that “if there be no faith among the children of men God can do no miracle among them” (Ether 12;12) (See also 1 Nephi 7:12)’ (Dallin H Oaks, General Conference, April 2010)
‘When you feel overwhelmed by expectations and challenges, do not fight the battle alone. Follow the example of small children, and drop to your knees in prayer. Jesus Christ has commanded us, “Look unto me in every thought; doubt not, fear not.” (D&C 6:35). Doubt, fear, and worry indicate we have taken all of life’s burdens and anxieties on ourselves. When plagued by thoughts that you are inadequate, confidently say, “I can do all things through Christ which strengtheneth me.” (Philippians 4:13, see also 1 Nephi 7:12). Then as you “cheerfully do all things that lie in [your] power,” (D&C 123:17) you can rest assured that the Lord will do the remainder and things will work out all right. “ (Anthony D Perkins, General Conference, October 2006)
“When our lives are consistent with his gospel, we receive confidence through his Spirit to meet the challenges of each day. We can say with Nephi: “The Lord is able to do all things according to his will, for the children of men, if it so be that they exercise faith in him. … Wherefore, let us be faithful to him.” (1 Nephi 7:12) (Rex D Pinegar, General Conference, October 1980)
‘Nephi’s exhortation to faith is somewhat unusual in Old Testament vocabulary. Faith is more often associated with the New Testament than with the Old. However, faith has never been absent in human experience regardless of the term we might use to define it. In the Old Testament, what we might term faith would be considered loyalty. One was loyal to Yahweh’s cause. As a loyal servant, one would follow Yahweh’s commands. Regardless of the term Nephi might have used, he had learned a significant lesson about faith and includes it in his conclusion. Nevertheless, we must remember that Joseph Smith’s translation was significantly influenced by his Christian and New Testament perspective. Thus, New Testament phrases and vocabularies appear in pre-Christian contexts in the Book of Mormon. Faith was likely one of those terms adopted from the New Testament context.’ (Brant Gardner, Second Witness – Analytical and Contextual Commentary on the Book of Mormon)
‘There is a reason that faith is the first principle of the gospel, because it is our willingness to believe Christ, to believe that He will do what He has said He will do, that activates the power of the Atonement in our lives. The Lord has promised “to do all things . . . for the children of men, if it so be that they exercise faith in him” (1 Nephi 7:12; emphasis added).
As our faith increases, we come to understand the magnificent promises He has made to those who live on His side of the line. He promised to heal our broken hearts and to set at liberty them who are bruised (see Luke 4:18, Jacob 2:8); to give power to the faint and to increase the strength of those who have no strength (see Isaiah 40:28–29); to help us bear our burdens with ease (see Mosiah 24:15); to succor us or come to our aid if we will seek after Him (see Alma 7:12); and to allow the devil no power over us if we will build our lives on His rock (see Helaman 5:12).
No doubt most of us here believe the Lord can do these things. But do we believe that He will? That He will heal our broken hearts and help us bear our burdens? The Lord has said that if we only “desire to believe,” we should let this desire work in us and experiment upon His words (see Alma 32:27). Can’t you almost hear the Savior pleading, “Try me. Put me to the test. See if I won’t do for you what I have said I will do.”
My testimony is that He will, and that He does. ‘ (Sheri Dew, BYU Speeches: Living on the Lord’s Side of the Line. March 2000)
