The scriptures teach us both directly and indirectly the power of a prophet in dispersing the darkness Satan sends to blind our eyes. The fifth chapter of Helaman recounts the story of Nephi and Lehi, who were bound in prison, awaiting their execution. When the Lamanites came to take their lives, they were "encircled about with a pillar of fire." At the same time, the Lamanites "were overshadowed with a cloud of darkness, and an awful solemn fear came upon them." (Helaman 5: 24, 28.) This cloud of darkness represents their spiritual state. The Lord was showing them an outward manifestation of their spiritual state. We are told that "they could not flee because of the cloud of darkness." (Helaman 5:34.) There was, however, something powerful enough to penetrate the darkness and show them the way.
"Aminadab turned him about, and behold, he saw through the cloud of darkness the faces of Nephi and Lehi; and behold, they did shine exceedingly." Aminadab cried to the others trapped in the darkness, encouraging them to look to the one source of light visible to them. "And behold, there was power given unto them that they did turn and look; and they did behold the faces of Nephi and Lehi." (Helaman 5: 36-37.)
When the adversary sends his clouds of darkness, his temptations, his deceptions and deceits, we need only look to the faces of the prophets. Their light is strong enough to penetrate whatever clouds may come our way. But just as the Lamanites had to turn and look, so we must turn and look. The light is there if we desire it. If we seek it, wonderful promises are offered.
