As an English teacher, I have taught the use of literary devices in texts, in which light is often used as a symbol for truth. For example, in Orwell’s 1984, the protagonist, who struggles with finding truth in a totalitarian government, dreams of “the place where there is no darkness”.
In this reading, light as truth is identified as God – no longer even a symbol – God is light. In Him, there is no darkness. We must act and live in truth, avoiding sin that leads us away from the light. When we want to clearly see into a dark room, we turn on a light. When we struggle through the darkness of our minds and hearts, we must turn to God to help us see. He is the beacon to lead us and save us – – He is the way. May we always strive to live in the light.
