After the parenthetical word that explains in detail God's selection, this book, continuing ch. 8, speaks concerning the latter half of God's complete salvation in Christ. In this latter half, those who enjoy the first half of God's complete salvation are members one of another as the Body of Christ (v. 5). Furthermore, they have the living of the Body of Christ on the earth to express Christ in different localities (such as those enumerated in ch. 16) that the Triune God may be expressed in such a living, as taught in the five chapters of the holy Word in this section, which concern the various aspects of this living. The first half of God's complete salvation, revealed in chs. 1—8, is the procedure by which God achieves His purpose; the second half of God's complete salvation, revealed in chs. 12—16, is the purpose of God's complete salvation.
