To serve God’s eternal purposes and to prepare this land for Zion, God “established the Constitution of this land, by the hands of wise men whom [He] raised up . . . and redeemed the land by the shedding of blood” (D&C 101:80).

The Constitution of the United States was ratified in 1789. The priesthood of God was restored in 1829. Between those two dates is an interval of forty years. It is my conviction that God, who knows the end from the beginning, provided that period of time so the new nation could grow in strength to protect the land of Zion.
