History and Nature together constitute the realm of divine activity and revelation. This thesis is then illustrated and supported from the book of Joel. The occasion of the book of Joel is a severe natural catastrophe caused by a locust plague and drought. In the locust plague Joel sees the realization of the day of Yahweh, the fulfillment of the prophecies of his predecessors. Particularly significant for this thesis is the fact that Nature reveals and enacts Yahweh's purpose.
Nature is neither passive nor inanimate, but rather participates with History in the divine plan.
