One of the most important aspects of letting our light shine before men is this: in order to be light, we need to first be filled with light. Consider a lamp in the Bible times – in order to give light, it needed to first be filled with oil. In the same way, we were not designed to produce light; we were made to simply contain light. As we walk in relationship with the God who is Light, we are filled with light and can then be the “light of the world”!
In scripture we see that God is Light and Jesus is Light. It is almost shocking then when we hear Jesus say to His disciples, “You are the light of the world”! How does this work? Just like the moon can only be light as it reflects the light of the sun, so we as disciples of Christ can only be light as we reflect Christ. We have no light in ourselves. It is the very life and light of Jesus that is to shine through us!
