What is the key to living the Christian life? What sustains us in our suffering? How do we overcome accusations from the devil, the conscience, and world? It isn’t based on what we do, but in remembering and applying who Christ is to us, and who we are in Him. In this section of the Apostle Peter’s letter, he is reminding these suffering saints these truths to encourage and sustain them in a world hostile to Christ and His people.
