Todd Nighswonger and Spencer MacCuish continue guiding us through I Peter, Chapter 1, on the matter of our identity, but specifically our "primary" identity as given to us by God Himself, namely as "elect exiles". It is through this unique identity that we are to be like mirrors, reflecting God's mercy and grace to the world. They go on to discuss specific practices Peter writes in verses 13-22 that guide us as we mature together as the body of Christ, enabling us to accurately reflect God the Father.
