Nephi taught that by clinging to the word of God, as though it be a handrail, we would be able to avoid temptations and not lose our way in darkness. Thus, we would remain on the narrow path.
Love is the beginning, the middle, and the end of the pathway of discipleship. It comforts, counsels, cures, and consoles. It leads us through valleys of darkness and through the veil of death. In the end love leads us to the glory and grandeur of eternal life.
