Affirming that Alma taught after this order, the record says: “And Alma went and began to declare the word of God unto the church which was established in the valley of Gideon, according to the revelation of the truth of the word which had been spoken by his fathers, and according to the spirit of prophecy which was in him, according to the testimony of Jesus Christ, the Son of God, who should come to redeem his people from their sins, and the holy order by which he was called” (Alma 6:8).
“To Stand and Testify”
The theme of the verses that follow is that, of necessity, there must be authority that controls and governs the manner in which the gospel is taught. That system is announced anew in a modern revelation which declares that those “preaching the word” are to do so “saying none other things than that which the prophets and apostles have written, and that which is taught them by the Comforter through the prayer of faith” (D&C 52:9).
Thus as we teach from the scriptures we partake of their spirit, the spirit of revelation, and our minds are enlightened, and we are then able to expound, expand, and apply the message of heaven to the circumstances and situation of those we are teaching. The scriptures are the seedbed for revelation.
