As Christians, we are to reflect the light of truth to the world. Think of it as being a moon. We should position ourselves in the best place to reflect the light of the Father into the lives around us. Ideally, when people see us, they will see the reflected light of the Father and be drawn to Him.
We become better moons by spending more time in His word. We can reflect His light better when there is more of Him and less of us.
