The followers of Christ are to do the same work that Christ did when he was in the world. Isaiah prophesied of him, saying: "The Spirit of the Lord God is upon me; because the Lord hath anointed me to preach good tidings unto the meek; he hath sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound; to proclaim the acceptable year of the Lord, and the day of vengeance of our God; to comfort all that mourn; to appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called Trees of righteousness, the planting of the Lord, that he might be glorified."

Kristi efterfølgere skal gøre det samme arbejde som Kristus gjorde, da han var i verden. Esajas profeterede: “Den herre Herrens Ånd er over mig, fordi han salvede mig; han sendte mig med glædesbud til ydmyge, med lægedom for sønderbrudte hjerter, for at udråbe frihed for fanger og udgang for dem, som er bundet, udråbe et nådeår fra Herren, en hævnens dag fra vor Gud, for at trøste alle, som sørger, give dem, som sørger i Zion, højtidspragt for sørgedragt, for sørgeklædning glædens olie; lovsang for modløst sind. Man kalder dem retfærds ege, Herrens plantning til hans ære.”
