As soon as Adam and Eve had been cast out of the Garden of Eden, Moses 5:1-4 tells us, they set about the work of providing for their temporal needs according to the order given by God, started raising a family, and called on God.
Verse 5 says that God responded to their prayers by giving them commandments, to which the text explicitly goes out of its way to inform us that Adam was obedient.
Immediately after stressing Adam’s obedience to the commandments (presumably, yes, all of them), verse 6 begins the well known story of Adam being visited by an angel who teaches Adam the meaning of his ritual sacrifices.
I find it intriguing that the Book of Moses mentions that very early after the Fall, Adam is described as learning obedience, quickly followed by learning sacrifice. Note that the footnotes to verse 5 direct us to the Topical Guide entry for “obedience,” and the footnotes for verse 6 lead to the entry for “sacrifice.”
