But the conditions of a covenant did exist and it was a covenant of works. It was not a covenant of grace which is a unilateral covenant, meaning it places no requirements on the covenant participants,but only on God to meet the promises of the covenant.
The new covenant is unilateral. A covenant of works. is a bilateral covenant. Meaning God initiates the covenant and its conditions for Him to fulfill the promises in the covenant, and stipulates the penalties for the participants not meeting the conditions.
Gen 2:15-17 The Lord God took the man and put him in the garden of Eden to work it and keep it. And the Lord God commanded the man, saying, "You may surely eat of every tree of the garden, but of the tree of the knowledge of good and evil you shall not eat, for the day that you eat of it you shall surely die." That is a covenant command. The promise of the covenant is the tree of life, mankind having dominion over the creatures, and the care of the garden, to be done so in submission to Him. Adam was planted (placed) into the promise, whereas his progeny do to the fall are not. Adam was created righteous. The covenant breaker would be disobedience to the command and gaining the knowledge of evil. The consequences were losing access to the tree of life, for then humanity was a sinful, not a righteous, being. The ground was cursed, pain and conflict and suffering entered humanity, and the serpent was cursed. And the future promise made---her Seed will crush your head. And that Seed is the only way out of the condition Adam placed mankind in. And how did He do it. By faithfully meeting every requirement of the covenant of works, including that of the Mosaic covenant law. I think you have a misunderstanding of "works."
Perfect personal, perpetual obedience is required. And no one can meet the requirement.Enter the Lamb of God who takes away the sins of the world. That is exactly the place the covenant of works meets the Redeemer who supplies perfect righteousness, substitutes Himself for the sinner on the cross, and where the doctrines of imputation and justification in the covenant of grace come from. The covenant of works. Grace and truth come through Christ. Mercy and justice kiss on the cross.
Only those misrepresenting the covenant of works say that. The actual covenant of works does not say that.
