Christ is “the true light that lighteth every man that cometh into the world…” (D&C 93:2)
The Priesthood is like a spiritual power of attorney given by God to mortals. With this power a man can teach with authority, heal the sick, perform miracles, administer the saving ordinances, and regulate the affairs of the Church, just as the Savior would do if he were present. In a sense, the priesthood is the power to think God’ thoughts, to speak his words, and to be his hands.” –Elder Tad R. Callister
So literal is the power to think his thoughts that the Savior said, “Speak the thoughts that I shall put into your hearts, and you shall not be confounded before me” (D&C 100:5).

So literal is the power of God’s hands that when Edward Partridge was called to be a missionary, the Lord said regarding his setting apart, “And I will lay my hand upon you by the hand of my servant Sidney Rigdon.” (D&C 36:2)
On one occasion, Nephi spoke with such commanding force that the disbelievers “were angry with him, even because he had greater power than they, for it were not possible that they could disbelieve his words.” (3 Ne. 33:1)
Men who held the priesthood taught the gospel truths with a persuasive and piercing power that “carrieth it unto the hearts of the children of men.” (2 Ne. 33:11)
“And we ask thee, Holy Father, that they servants may go forth from this house armed with thy power, and that thy name may be upon them, and thy glory be round about them, and thine angels have charge over them; And from this place they may bear exceedingly great and glorious tidings, in truth, unto the ends of the earth, that they may know that this is thy work, and that thou hast put forth thy hand, to fulfill that which thou hast spoken by the mouths of the prophets, concerning the last days.” (D&C 109:22-23)
