"I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life."
Think on the different functions of light
and how the Savior literally is the Light.
It illuminates and enables one to see.
As we view life through the Savior's light, the better path comes into view and we can walk in God's confidence. Otherwise undetectable pitfalls come into view and we are able to choose the safety and assurance of the Savior's way. His light illuminates the mind with understanding.
It nourishes and sustains life.
In plants, light initiates photosynthesis. In humans, it triggers the body's production of vitamin D. The Savior's gospel is the essential nourishment for the soul. Striving to follow His example and apply His teachings triggers life giving processes deep within the core. As we continually seek and receive His nourishment ... our spirit becomes enlarged and life thrives within.
I remember my grandmother laying her whites out in the sun to bleach them. In turn, the Savior's light is SO pure and SO potent that our natures can't help but be sanctified as we bask in His light.
It warms and comforts.
For me, I experience a physical sensation of warmth and fulness in my heart when I think on the Savior. His love soothes the aching soul. His words speak comfort and hope to all who seek Him.
It overcomes darkness.
Darkness and light cannot exist in the same space. In Christ's presence, Satan flees. Confusion and deception cannot withstand "the Truth" (Jesus Christ) which sets our minds and vision free.
Red blood cells are drawn to light enabling damaged tissue to heal. The Savior suffered unspeakable pain which caused Him to bleed from every pore... that the door to our healing might be unlocked.
"But he was wounded for our transgressions, he was bruised for our iniquities:
the chastisement of our peace was upon him; and with his stripes we are healed. "
Under bright light; detail, flaw and impurity otherwise unnoticeable comes into view. Under the Savior's revealing light, flaws within our character come to our awareness. As we press forward in Christ, we will resist the temptation to feel overwhelmed and hopeless because of our weakness. We will rather glory in our infirmities that the power of Christ may rest upon us. (see 2Cor 12:9-10) We will rejoice in His companionship as we struggle and work to apply the healing power of the atonement to those impurities. We will recognize that when we are weak , then are we strong... through Him that redeems us.
