Revelation...is progressive, i.e., cumulative. God has not revealed Himself comprehensively at any one stage in history or in any one event. Revelation is a series of divine disclosures, each of which builds upon and unpacks or unfolds that which preceded it. Revelation moves from what is piecemeal and partial and incomplete (but always accurate) to what is comprehensive and final and unified. This contrast between the incomplete and complete, between the partial and the full, is not a contrast between false and true, inaccurate and accurate, but a contrast between shadow and substance, between type and antitype, between promise and fulfillment.
