SAVIORS ON MOUNT ZION

There is some great doctrine taught here:

John A. Widtsoe taught,
“In our preexistent state, in the day of the great council, we made a[n] … agreement with the Almighty. The Lord proposed a plan. … We accepted it. Since the plan is intended for all men, we became parties to the salvation of every person under that plan. We agreed, right then and there, to be not only saviors for ourselves but … saviors for the whole human family. We went into a partnership with the Lord. The working out of the plan became then not merely the Father’s work, and the Savior’s work, but also our work. The least of us, the humblest, is in partnership with the Almighty in achieving the purpose of the eternal plan of salvation.”

“That places us in a very responsible attitude towards the human race. By that doctrine, with the Lord at the head, we become saviors on Mount Zion, all committed to the great plan of offering salvation to the untold numbers of spirits. To do this is the Lord’s self-imposed duty, this great labor his highest glory. Likewise, it is man’s duty, self-imposed, his pleasure and joy, his labor, and ultimately his glory.” (“The Worth of Souls,” The Utah Genealogical and Historical Magazine, Oct. 1934, p. 189.)
