Two-Stage Fulfillment: King, People and Land

…Another aspect of the discontinuity between them [Old and New Covenants] emerges when they are viewed as two stages in the fulfilling of the kingdom promise of the Abrahamic Covenant. The Old Covenant kingdom is only a temporary type, a provisional symbol, while the New Covenant kingdom is the permanent antitypical reality. Emphasizing this difference, the Book of Hebrews declares the discontinuity to be such that with the initiating of the New Covenant, the Old Covenant becomes obsolete and vanishes away (Heb. 8:13). To be sure, a certain continuity is involved in the typological relationship itself, the continuity of the earlier prototype to the later antitype of promise to fulfillment. Nevertheless, the New Covenant fulfillment entails the discontinuance of the Old Covenant. The Old Covenant is abrogated and replaced by the New Covenant (cf. Heb 7:18; John 1:17; Rom 10:4). At the same time, we recognize that there is solid continuity between the Old and New Covenants when the Old Covenant is viewed not as the overlay stratum to which the typological kingdom and works principle appertain but at the foundational gospel-grace layer. Indeed, from this perspective the New Covenant continues the Old Covenant.
