“ In our own day He has said, The whole world lieth in sin, and groaneth under darkness and under the bondage of sin. by and large the modern world has not come unto Him, has not accepted the atonement of Jesus Christ, has not received the voice of His prophets, has not made covenants or kept His commandments, has not remembered Him always or claimed the promises of exaltation in the kingdom of heaven. So He has offered us one last covenant, given us one last testament, as part of His final outreach to fallen man. He has offered us one last written witness of His love and His mercy extended for the final time, speaking dispensationally. As one Book of Mormon prophet foresaw it, God is sending laborers into the vineyard one final time, and then cometh the season and the end. That testament and culminating witness, that new covenant offered to the children of men but once more, is the message of the Book of Mormon. ”
