Sunlight is responsible for all life, including the air we breathe & a plethora of other life sustaining necessities. The sun can be an underestimated source of power. For example, not only does it produce life, but it also has the ability to destroy that which comes into its direct path. Jesus' testimony in John 8:12-21 proclaims that He is "The Light of Life". Not only does His Light guide us toward eternal life, but also eternal seperation for those who reject His testimony.
