This beautiful, profound, and challenging first chapter of 1 Peter lays the foundation for the rest of Peter’s letter. In spite of whatever suffering we may face, God Himself has already shown us great mercy in Christ by including us in His family! Jesus is our living hope. Our future is secure and endless and perfect. As the children of God we have every reason to rejoice, even in this present darkness. Peter then calls us to prepare ourselves to live as the holy people God has made us to be.
