Thus Saith the Lord

Everything I know indicates that when God speaks, He does so to the living prophet. Each of us can receive revelation, but very few have heard the actual voice of God. Those who do hear God's voice are righteous.

Here's my question: would God speak directly to a murderer, one who "loved Satan more than God"?

I don't think so. Yet, that is what many understand from the story of Cain.

Background: Adam and Eve have many children, and teach them the Gospel (Moses 5:12). Adam is the prophet on the earth. Adam and Eve have two more children, Cain and Abel. Cain is wicked, while Abel is righteous. Satan commands Cain (who probably was not authorized with the priesthood) to make an offering to the Lord (using the "fruit of the ground"--a perversion of the ordinance). He does so; Abel also makes an offering (the right way). The Lord (THE LORD in the KJV Bible--indicating that the words are a replacement of the name Jehovah) "had respect unto Abel, and to his offering; But unto Cain, and to his offering, he had not respect." (Moses 5:20-21)

I suggest that the reason Cain knew that the Lord didn't approve of his offering was because Adam, the prophet, said as much.

Then in verses 22-25 of Moses 5, the Lord speaks to Cain. After Cain kills Abel, the Lord again speaks to him in verses 34-40. It seems strange to think that Jehovah would speak to a murderer and given that we have no record of Adam speaking to his son about these things, I think that the Lord was speaking through His prophet, Adam, just as He has done with many prophets and even Joseph Smith in many sections of the Doctrine and Covenants.

In verse 26, we read, "And Cain was wroth, and listened not any more to the voice of the Lord, neither to Abel, his brother, who walked in Holiness before the Lord." Why doesn't it read, "neither to Adam, his father"? It wouldn't if the voice of the Lord was given to him through Adam.

It does make sense that Adam would speak to his son about these things.

Last thoughts for now:
This topic is much like my entry on Adam's creation; it is very speculative and unconfirmed by any published doctrine that I know. It does make sense to me, though. I think Adam was directly involved in his sons' lives, and I think he gave his children the words of the Lord as their prophet.
