4. One flock, one body, one new man, the wall is down and stays down

From Sovereign Grace and the Scope of Election: A Comparative Examination of Attainment Theology and Grace Theology, with Particular Attention to the Question of Whether God's Elect Are Found Among All Nations and Religions

The dispensational scheme requires God to maintain two peoples on two tracks, an earthly Israel with earthly promises and a heavenly church with heavenly ones. Ephesians 2 demolishes the architecture by name: Christ "hath made both one, and hath broken down the middle wall of partition between us... for to make in himself of twain one new man, so making peace" (2:14-15); Gentiles are "no more strangers and foreigners, but fellowcitizens with the saints" (2:19), "fellowheirs, and of the same body" (3:6). A theology that rebuilds the partition wall in its prophecy charts is repairing what Christ died to demolish (compare Galatians 2:18: "if I build again the things which I destroyed, I make myself a transgressor"). Jesus foretold precisely this single-flock outcome: "other sheep I have, which are not of this fold: them also I must bring... and there shall be one fold, and one shepherd" (John 10:16), one, not two on parallel timetables.
