This is an excellent article, and I commend you for posting it. It proves that the OP is flawed, since there is not a consensus among dispensationalists, therefore any way you interpret the new covenant is not really a strictly dispensational viewpoint.
OR.....it proves dispensationalism was D.O.A. and after it was shown to be flawed, a mad scramble has gone on, all kinds of damage control, trying to repair the breaches.....so we get doublespeak, partial fulfillment when the scripture indicates no such thing.
It is defective it it's view of the Covenants, and must seek to explain away that which holds it all together.
KYRED SAID;
There's something flawed with there not being a consensus among dispensationalists.
Originally there was......then when it got picked apart they had to change it.
Even those who offered it up front felt the pressure and could sense the mistakes in it....to their credit, they did try and address it like here;
14Commenting on the new covenant in Jer 31:31–34, Chafer notes: “There remains to be recognized a heavenly covenant for the heavenly people, which is also styled like the preceding one for Israel a ‘new covenant.’ It is made in the blood of Christ (cf. Mark 14:24) and continues in effect throughout this age, whereas the new covenant made with Israel happens to be future in its application. To suppose that these two covenants—one for Israel and one for the Church—are the same is to assume that there is a latitude of common interest between God’s purpose for Israel and His purpose for the Church. Israel’s covenant, however, is new only because it replaces the Mosaic, but the Church’s covenant is new because it introduces that which is God’s mysterious and unrelated purpose” (Systematic Theology, 7:98–99).
