Light verses dark - what is light? it is fire - the sun burns gases, and emits light, wood burns and emits light, you must heat an metalic filament to get the glow in a light bulb (or burn gases). When it comes right down to it, light is FIRE. Light has properties and affects like it illuminates objects making it visibile to our eyes; it has heat; it is a wave and a particle. In order for light to exist it needs an energy source, like gas, or wood as mentioned. But what if light's energy source was Jesus? What does that look like to us?
