Jesus the Christ told us, "You are the Light of the world...Let your Light so shine." He wasn't speaking metaphorically for we are indeed Beings of Light. Though we most often associate ourselves with our bodies, we are not these bodies, we are Spirit. Dive deep into any great spiritual teachings and you will find this common theme. We are the Essence created by God. The more we dwell on this thought and seek to live from it, the greater our own happiness and the more "Light" we bring to the world. This is, in fact our mission here just as it was for the Master Jesus.
