From the early 1650s Reformed theologians began to speak explicitly of the “covenant of works” to describe God’s relations to Adam (and us) in the garden and to explain the nature of the demands of the law upon God’s image bearers. In this second video on the covenant of works, Dr Harrison Perkins explains a bit more about the law as God’s standard of righteousness in the covenant of works.
If all men already have the law in our ‘dna’, then how does the law written on our hearts from creation differ from the ‘new’ law written on our hearts from Jer.31?
I don’t think it does in substance. What changes is our relationship to the law.
