Christ, the Light of the World


"I am the light of the world.  He who follows me shall not walk in darkness, but have the light of life." (John 8:12)


"In [Christ] was life, and that life was the light of men.  The light shines in the darkness, but the darkness has not understood it." (John 1:4-5)


"For you were once darkness, but now you are light in the Lord.  Live as children of light (for the fruit of the light consists in all goodness, righteousness and truth) and find out what pleases the Lord.  Have nothing to do with the fruitless deeds of darkness, but rather expose them.  For it is shameful even to mention what the disobedient do in secret.  But everything exposed by the light becomes visible, for it is light that makes everything visible.  This is why it is said, 'Wake up O sleeper, rise from the dead, and Christ will shine on you.'" (Eph. 5:8-13)


Light is an amazing component of our universe.  Nothing in the universe travels faster than the speed of light (Star Trek warp speed notwithstanding!). Special relativity tells us that the speed of light is independent of the motion of the observer (that is, to an observer traveling 1 meter per second slower than the speed of light, an object traveling the speed of light would still appear to be traveling at the speed of light!).  Light has a dual nature that has confused physicists until modern times:  it behaves as both a wave and as a particle. 


Einstein among others showed that light consists of "particles" called photons that have energy (but no mass). However, light has many wave-like properties such as refraction (seen, for example, when light bends through a prism).  Of course, light enables us to see, and the wavelength at which light radiates determines what color we see.  And light (sunlight) enables plants to undergo photosynthesis, which is essential to life (plant, animal, and human) on Earth.  From a physical standpoint, then, light is absolute, mysterious, sight-enabling, life-giving, and -- without a doubt -- wondrous!


From a spiritual standpoint, the Light of the World -- Christ -- is equally wondrous.  Christ is the Light who forms the absolute standard that discerns the thoughts and intentions of the hearts of men. Christ is the Light who is mysterious (1 Tim. 3:16), dual in nature, both human and divine.  Christ is the Light who illuminates the spiritual darkness of this world, forcing those who do not know Him to flee back into the shadows and yet enabling those who DO know Him to see and to understand the things of God.   And Christ is the Light who gives us eternal life,

for He is the Way, the Truth, and the Life.  In the world we live in today, with so many uncertainties and so much evil, Christ is the only answer to the questions of life.  Let us turn to Christ, the Light of the World.


In Christ,
