This is part 4 of the series: I Will Be A God To You And To Your Children. Last time we considered whether it’s right to speak of a “covenant of grace.” We saw that, from the very beginning of redemptive history, immediately after the fall, God made a promise to Adam, a covenant, to send a Savior and he administered that promise through Noah, Abraham, Moses, David, the prophets, and finally fulfilled it in his well-beloved Son, Jesus. In this episode we’re thinking about what ties the covenant of grace together under the types and shadows and under the new covenant. The way one of our earlier covenant theologians spoke was to speak of the substance of the covenant of grace as distinct from its accidents. This is an older set of categories. Substance refers to that which makes a thing what it is. What is it that makes a car what it is? It has an engine, it has wheels, it has a place to sit, and a way to steer. The color, the number of seats, the size of the engine and the number of wheels (e.g., 3 or 4) doesn’t change its essence. Those things affect what sort of car it is but not whether it is a car.
