The Father told Him to go down and do certain things. He knew how to do them because He had seen the Father do them. He is the great eternal Christ, the Word of the living God, the Son of the Father, the first-born of all the children of God that afterwards tabernacled here on the earth. He was not Adam; Adam was not He: He gave commandments to Adam in the Garden. Adam worshiped the Father, and we worship the Father: we do not worship Adam. Adam is the head of the race, so far as the temporal body is concerned. He is placed at the head, as you will read in the Doctrine and Covenants in section 107.
