Spiritual labor is its own reward, a labor not motivated by the idea of temporal remuneration. Those who “receive the grace of God,” who seek and obtain the guidance of the Holy Spirit, come to have “the knowledge of God.” They gain “the mind of Christ” (1 Corinthians 2:16); they receive “pure knowledge” (D&C 121:42), knowledge from a pure source; and they come to know things about God and about God’s purposes and ways that others will never know. When they speak, therefore, they speak as persons having authority; being fit receptacles, they speak with the power and authority of their Master.
