I have been drawn to the subject of 
light lately.  I find myself frequently pondering upon the words "sun" 
and "son," and marveling at their similarities.  For example, we look to the sun 
to provide light, warmth and life.  Likewise, we look to our Savior, the Son of 
God , to provide light (3 Nephi 19:25), warmth (3 Nephi 
19:13), and Eternal life (Romans 6:23). Last fast and testimony 
meeting, I was thinking about the concept of
 light with regards to 
testimonies, and I wondered to myself, "How can someone say I KNOW the Gospel of 
Jesus Christ is true?"  Suddenly the image of the sun entered my mind, and I 
began to contemplate on how I KNOW the sun is real.  I KNOW the sun is real 
because it rises everyday, but really that fact alone isn't enough.  It occurred 
to me that the sun could rise and set without me even knowing it was there if it 
wasn't for the 
warmth and 
light it provided.  Because of this 
warmth and 
light that I tangibly feel and see everyday of my 
life, I can say with perfect knowledge, I KNOW that the sun is real.  
Then I began to ponder upon how I KNOW the gospel of Jesus Christ is 
true, and how I KNOW that Jesus Christ is my Savior.  And I discovered that I 
KNOW these things are true because, just like the sun, the 
light of 
Christ powerfully rises within me and radiates in my countenance to all those 
around me when I choose to follow the Savior's teachings.  I am then blessed 
with the 
warmth and peace of the Holy Ghost which greater testifies to 
me of my Savior's existance and His plan.  Oppositely, when I do not follow the 
principles taught by our Savior, I am dark and inwardly it feels like my life is 
void of the sun.  Simply put, when I follow the Son, I feel 
light. When 
I choose to stray from the Son, I feel darkness.  
So, just as perfectly as I KNOW the sun is real, I 
KNOW that The Church of Jesus Christ of Latter-day Saints is God's true church 
on earth, and Jesus Christ is my Savior. 
Mosiah 
16:9  "He is the 
light and the life of the world; yea, a 
light that is endless, 
that can never be darkened; yea, and also a life which 
is endless, that there can be no more death."  As a side note, don't you love 
that the one day we have dedicated to full worship of our Savior is called 
"Sun"day.
