Was the Covenant of Works Gracious?

The Covenant of Works was gracious (kind and good), apart from sin.  God can only reach down to his creation in his condescension and be the total giver of promise and life.  But that condescension was intolerant of sin. 

The creation was transcended in plan by the Covenant of Grace.  It was planned from eternity past, in the Lamb slain from the foundation of the world, and was ready when Adam fell.

Although Adam believed, he still died.  As a result of his sin millions died who did not believe.

Adam and Christ are two heads.  The Apostle takes pains to contrast the effects of the lives of these two Men (Rom 5, I Cor 15).

However much it is the absolute, overriding and vital truth that grace superabounds where sin abounds, and that the Covenant of Grace is the transcendent covenant, nevertheless it must be the case that these two Men represent two covenants.

God has mercy upon whom he will.  But, not all who were in Adam live.
