This has come to pass. The powers of earth cannot withstand the privileges and bestowals which God has ordained for this great and glorious century. It is a need and exigency of the time.... Let this century be the sun of previous centuries, the effulgences of which shall last forever, so that in times to come they shall glorify the twentieth century, saying the twentieth century was the century of lights, the twentieth century was the century of life, the twentieth century was the century of international peace, the twentieth century was the century of divine bestowals, and the twentieth century has left traces which shall last forever.
