There is so much Peter tries to communicate to the church in this letter, but this passage highlights 2 of Peter’s more important points. First – we are to be the light in a dark place. We are to shine the light of God in all we do for all to see. When we get up in the middle of the night for whatever reason and start moving around the house, the one single nightlight illuminates huge rooms enough for us to fine our way without bumping a toe. We don’t have to be a big light, or a beautiful lamp that shines or even a particularly smart light – just a light, any light that reflects the love of God can accomplish huge illumination for a dark world to find its way. When it is dark, really dark, we are drawn to the simplest of lights and are grateful to have them.
The same is true when we are the light for the world – keep the message simple. People don’t need complicated theologies, they just need the love of God.
