Man, as made in the image of God, is intrinsically (by default) "wired" as a covenantal being. He knows of himself as a covenantal being and, though after the Fall, the sinner lives and moves in suppression of this fact, still he cannot escape it in the voice of his conscience and in the testimony of creation all around him.
What this covenatalism further presupposes is that both natural and special revelation bear upon man's conception of anything. Natural revelation both reveal the grace and wrath of God in the consistency of life-support systems in creation as well as the death dynamic that is at work in it, just as special revelation reveal the grace and wrath of God in the person and work of Christ and in the final, eschatological death that is alluded to by physical, temporal death. Man, as man, needs both natural and special revelation.
This realization has given me pause about NL2K (Natural Law Two Kingdoms Theology, or sometimes R2K). Sure, the baker does not need special revelation in order to engage in his baking, but this is merely speaking at a practical level. The baker, as an ontological human being made in the image of God, has upon himself the covenantal duty to reckon with both God's natural and special revelation at every turn. Is there an occasion wherein the baker does not bake as a human being? If not, then even in his baking, special revelation is required if he is to bake as a human being. What NL2K seems to imply is that there are two species of human beings, one for whom both natural and special revelation are of import and another wherein natural revelation will do. But the Fall did not create two different ontological classes of human beings but two different covenant relations to God in which man could either be a covenant-keeper or covenant-breaker (the antithesis). So when the baker bakes unmindful of God in special revelation, he bakes as a covenant-breaker and in fact sins in his baking.
To be sure, God uses the covenant-breaking baker to provide carbohydrate energy to both sinner and saint alike, but this is merely an outworking of His patience, intending the order and consistency in the present age to facilitate the smooth unfolding of redemptive history that will culminate in the age of glory characterized by revelational integrity.
