Doctrine & Covenants
Section 2
Jehovah announces that before the great and dreadful day of His coming, He will restore the Priesthood through Elijah — the same Elijah who held the sealing keys of the Holy Order in an earlier dispensation. The mission of that restoration is specific: to plant covenant promises in the hearts of the rising generation so that their hearts turn toward the covenant fathers. Without this turning — without the lineage-chain of covenant being rejoined across generations — the earth itself would be forfeit at His coming. The stakes here are not devotional; they are the legal condition for Zion's establishment.
1
Behold, I will reveal unto you the Priesthood, by the hand of Elijah the prophet, before the coming of the great and dreadful day of the Lord.
2
And he shall plant in the hearts of the children the promises made to the fathers, and the hearts of the children shall turn to their fathers.
3
If it were not so, the whole earth would be utterly wasted at his coming.
