This book explores the importance of the tribe of Ephraim and the lost tribes of Israel in regards to the establishment of Zion in the last days. In the restoration of all things spoken of by the prophets of old, God will bring about the restoration of the whole house of Israel, gather the lost tribes to a place of refuge, and set up an ensign for a witness to the world. This event is known by several names, including: the great and marvelous work, the work of the Father, and God's strange act. This is a mystery that has been hidden from the world, but its time is nearly upon us. This is the second edition of this book, originally entitled: "God's Strange Act."
