Key Takeaways
1. Light's Dual Nature: Physical and Spiritual
The purpose of this book is to provide spiritual edification.
Beyond the visible. Light is far more than what our physical eyes can perceive. From the profound darkness of Carlsbad Caverns to the invisible forces powering our modern world, light encompasses a vast spectrum of electromagnetic radiation. This book explores the deep connections between what science empirically knows about light and what spiritual doctrine reveals about its eternal significance.
Diverse applications. Light is fundamental to nearly every aspect of our lives, both seen and unseen.
- Light and Dark: A primal dichotomy representing good versus evil, comfort versus fear.
- Light and Heat: Invisible infrared radiation emitted by all objects above absolute zero, hinting at a "spiritual body radiation."
- Light and Communication: The ubiquitous medium for transmitting information, from the internet to cell phones, mirroring God's ability to communicate.
- Light and Life: The sun's light enables photosynthesis and warms the Earth, paralleling Christ's life-giving power.
A spiritual lens. By examining light through both scientific and spiritual lenses, we gain a richer understanding of its pervasive influence. The author's journey, sparked by a college physics course and seminary studies, reveals that physical principles of light can illuminate gospel truths, offering a new "light" on this eternal power.
2. The Science of Light: A Glimpse into God's Order
What befuddled the world’s best scientists one hundred years ago about light was how something intangible could move in a specific direction (even though it is a wave), and at the same time do something physically tangible, such as cause an object of some type to heat up (suggesting that light is a particle).
Wave-particle duality. Light, scientifically termed "electromagnetic radiation," exhibits a perplexing wave-particle duality. It propagates as a wave (a combination of orthogonal electric and magnetic fields) but also acts as discrete particles called photons, each carrying energy and momentum. This fundamental paradox highlights the complexity of light, even for Nobel laureates like Richard Feynman.
Fundamental constants. Light's behavior is governed by universal constants, such as Planck's constant (relating energy to frequency) and the speed of light (the fastest known speed in the universe). These constants, alongside others like gravity and electromagnetism, underscore the inherent order and design in the cosmos, testifying to a Supreme Creator.
- Energy: Measured in electron volts (eV), akin to battery voltage, enabling light to "do work" like photosynthesis.
- Frequency & Wavelength: Inversely proportional, defining different types of light across the electromagnetic spectrum.
- Speed of Light: A constant (c) that interrelates space and time, with profound gospel relevance.
Sources of light. Light is not stored but generated through energy conversion.
- Thermal Radiation (Incandescence): Heat energy converted to light (sun, fire).
- Electric Discharge: Electrons interacting with gas molecules (lightning, fluorescent lamps).
- Luminescence: Light emission from non-thermal sources (chemical, photo, electro, bio), hinting at "spiritualuminescence."
3. Spiritual Body Radiation: Our Constant Influence
Every man, every person radiates what he or she is. Every person is a recipient of radiation.
Universal emission. Just as all physical objects above absolute zero emit "blackbody radiation" based on their thermal energy, our spirits, being "more fine or pure" matter, emit a form of "spiritual light" based on spiritual energy. This radiation is constant and inescapable, influencing everyone around us.
The Holy Ghost as fuel. One hypothesis suggests the Holy Ghost acts as the spiritual energy source, fueling the Light of Christ within our souls. Our obedience and righteousness reduce "resistance" to this spiritual energy, allowing the Light of Christ to shine brighter.
- Light of Christ: An inherent, luminescent source within every soul, providing conscience and potential for godhood.
- Holy Ghost: The spiritual "battery" that, when yielded to, amplifies the Light of Christ's radiance.
- Obedience: Acts as a "resistor," determining the brightness of our spiritual light; greater obedience means less resistance.
Let your light shine. The Savior's command to "let your light so shine before men" takes on new meaning, emphasizing active directionality and the removal of "bushels" (sins, apathy, fear) that block its reach. Our spiritual radiation is a powerful, unconscious influence, shaping perceptions and glorifying God through our good works.
4. Sensing Spiritual Light: Discernment Beyond the Physical
Faith emits a spiritual light, and that light is discernible.
Invisible detection. Just as X-rays reveal hidden structures, our spirits can detect invisible spiritual light. The "more fine or pure" matter of our spirits, combined with our physical bodies (the "substrate"), enables unique interactions with spiritual light, amplifying our ability to grow eternally.
The soul's capabilities. Our souls are capable of interpreting far more than just the intensity or wavelength of light.
- Emotional Detection: Sensing others' pain, peace, or discomfort through their presence alone.
- Spiritual Sight: Noticing a "glow" or "light in their eyes" in righteous individuals, often a catalyst for conversion.
- Unconscious Influence: Our spiritual radiation is constantly influencing others, regardless of their awareness or our intent.
Looking for light. Actively seeking and acknowledging the light radiated by others—especially in close relationships—fosters positive interactions and fuels their spiritual growth. This practice helps us see others as the Savior sees them, reinforcing the good within them.
5. Information within Light: God's Communication Channel
Incredible amounts of data/information can be packed into light.
Digital communication parallels. Modern technology digitizes vast amounts of audio and video data, encoding it into light by modulating attributes like intensity, frequency, phase, or polarization. This information-packed light is then transmitted and retrieved by intended receivers, demonstrating light's capacity for complex communication.
Spiritual information transfer. If human-made technology can achieve such feats, God's perfect understanding of light allows for infinitely more profound communication. Spiritual light can carry:
- Thoughts and Feelings: Telepathy-like connections across distances, as seen in shared memories or prayers.
- Intentions and Directions: Divine guidance and promptings.
- Scriptures and Truths: The inherent link between light, truth, and knowledge.
Discerning truth. The Holy Ghost amplifies our ability to detect and decipher information within spiritual light. Discerning truth from light requires:
- Belief: Choosing to believe a truth.
- Faith: Exercising faith in that truth.
- Witness: Receiving confirmation from the Holy Ghost.
- Understanding: Comprehending the truths associated with the light, leading to "perfect knowledge in that thing."
6. Light's Power: Moving, Burning, and Protecting
Light has momentum that is directly proportional to its energy.
Physical force of light. While individual photons have minuscule momentum, a concentrated beam of high-energy, high-intensity light can transfer significant energy, capable of heating, moving, or even destroying objects. This principle is demonstrated in military laser weapon systems.
Divine protection. Scriptural accounts suggest God uses light's power to protect His servants:
- Samuel the Lamanite: Protected from stones and arrows by the "Spirit of the Lord," possibly through light's momentum deflecting projectiles.
- Abinadi: His face shone with "exceeding luster," and those who tried to seize him were physically repelled, indicating a powerful, unseen force.
Second Coming's light. The Lord's Second Coming will be accompanied by glorious, overwhelming light. This light will not be a wrathful act of vengeance but a natural consequence for the unprepared.
- Burning Effect: "The brightness of my coming" will consume the wicked, not as a punitive act, but because they cannot withstand the intensity of God's pure light.
- Preparation: Growing in spiritual light through obedience prepares us to "abide the day" and see Him "as he is" without being consumed.
7. Purification by Light: Cleansing the Soul for Discernment
The glory of God is intelligence, or, in other words, light and truth. Light and truth forsake that evil one.
Cleansing power. Just as ultraviolet (UV) light purifies water by destroying microorganisms (UVGI), spiritual light possesses a purifying power for the soul. It cleanses us from "impurities" like sin and doubt, fostering spiritual health.
Sanctification through light. The Holy Ghost catalyzes our sanctification by fueling our radiation of truth and light, which "forsakes that evil one." This process is made possible by the Atonement of Jesus Christ, allowing us to stand "spotless" before Him.
Increased discernment. Spiritual purification leads to enhanced discernment.
- Comprehension: Moving beyond merely sensing light to understanding the truths associated with it.
- Perspective: A purified heart grants a clearer, brighter perspective on our spiritual surroundings, much like increased physical light reveals details in a dim room.
- Helen Keller's Example: Her journey from darkness to profound discernment, activated by "light to her soul," illustrates how understanding can transcend physical senses.
Lasting conversion. Discernment of spiritual light, fueled by the Holy Ghost, creates an indelible impression on the soul, unlike fleeting physical signs. This truth, woven into our very being, cannot be easily forgotten and empowers us to navigate a darkening world.
8. The Eye Single to God: Filling Our Bodies with Light
And if your eye be single to my glory, your whole bodies shall be filled with light, and there shall be no darkness in you; and that body which is filled with light comprehendeth all things.
Focus determines perception. Our physical vision is complex, involving light entering the eye, being focused by the lens, and interpreted by the brain. Similarly, our spiritual "eye" determines what we perceive and comprehend spiritually. Our focus dictates what we see and learn.
God is light. John's declaration, "God is light, and in him is no darkness at all," is a literal truth, echoed across diverse religious traditions. God is the ultimate source of all light, and to become like Him is to be filled with light and devoid of darkness.
Eye single to His glory. This doctrine, repeated across scriptures, means focusing our spiritual eye—our intent, motivations, and will—entirely on God.
- "Let God Prevail": Allowing His will, commandments, and voice to take precedence over all else.
- Spiritual Brightness: A detectable "light in their eyes" of the faithful, reflecting the Lord's light that "enlighteneth your eyes."
- Eye of Faith: Our spiritual portal to God, linking obedience with pure intent, leading to a "perfect heart and willing mind."
Comprehending all things. When our "mind[s] become single to God," our bodies are filled with light, enabling us to "comprehend all things." This process of continuous learning and obedience, like Nephi's unwavering focus, aligns our will with God's, preparing us to "see him as he is."
9. Jesus Christ: The Ultimate Source and Unifying Light
I bear witness that darkness cannot stand before the brilliant light of the Son of the living God!
The Grand Unified Reality. While science seeks a "Theory of Everything," the gospel of Jesus Christ provides the ultimate unified model: the plan of salvation, centered on the Savior. His Atonement is the infinite, eternal truth that unifies all knowledge and power.
Christ, the Light of the World. Jesus bears the title "light of the world" because He is the source of all light, both physical and spiritual. The Light of Christ is:
- Divine Energy: The power by which the sun was made, giving life and light to all things, governing all laws.
- Conscience: Guiding us to discern good from evil and leading us to the gospel.
- Vehicle of Atonement: The mechanism through which Christ's infinite love and atoning power reach all of God's children.
God's love and light. The Light of Christ is synonymous with the love of God, the ultimate manifestation of the Father and Son's love for us. It "sheddeth itself abroad in the hearts of the children of men," filling the immensity of space, inescapable and life-giving.
"Now I see." Our journey is to know God, feel His love, and embrace the Atonement. By trusting in God's light and obeying His commandments, we discern more truth, growing "brighter and brighter until the perfect day." When Christ returns, those prepared will not be consumed by His light but will see Him "as he is," reflecting His glory.
