Peter has described for us who we are, and our ultimate destiny. Now he describes for us how we are to live as we wait for Christ’s return. At the center of the command is the call to live as who we really are, but instead of being true to ourselves in the sense of following every desire (i.e. slave to sin) he calls us to be true to ourselves by living in sync with the new identity God has given us. We are CHOSEN, we are HOLY and we are CHILDREN of God.
