Is the Covenant of Works biblical?

Is the covenant of works biblical? For many western Reformed theologians, this is an old question. But for a young thinker like the blogger, I find time to explore this question only just now.

And so I read several articles on the subject written by Dr. J. Faber, R. C. Sproul, Wayne Grudem, Charles Hodge, Robert L. Dabney, Louis Berkhof, John Murray, and Shane Lems. I realized that these Reformed thinkers are divided on the issue particularly wether its continuous use is really consistent to the teaching of the Bible. 

I am done reading Dr. Faber's article. However, I intend to continue my survey of the subject. And so before I proceed to R. C. Sproul's articles, I want to use as an introduction the article from Monergism, which answered this specific question. 

The article does not deny the absence of the term "covenant of works" to describe God's relationship with Adam in the Garden of Eden. However, the anonymous writer believes that the idea is indeed biblical, and this is for five reasons:

"First, creation itself is portrayed in the scriptures as existing in a covenantal relationship with God (Jeremiah 33:20-26); and if creation in general is established in covenant with God, how much more must the climactic figure of creation, the man created in God's own image, necessarily be in covenant with God from his very creation?"

"Second, the account of man's creation in Genesis very clearly displays all the elements that characterize later covenants."

Third, the existence of a sacrament considered as a covenant sign, the Tree of Life.

Fourth, if the translation of Hosea 6:7 is accepted, it is clearly indicated there that a covenant was made with Adam.

Finally, the most weighty arugument is Romans 5:12-21, which the apostle Paul clearly stated that both Adam and Christ are covenant head or representatives.

Concerning the elements of the covenant, the article identifies four. These are the preamble, stipulations, negative sanction for disobedience, and reward for obedience. 

Those who are stumbled by the use of the term "Covenant of Works," the articles states that they prefer to use other terms like “Covenant of Nature,” “Covenant of Life,” “Covenant of Creation,” and “Covenant of Eden”.
