Key-word, “Faith;” Key-verse, 3:11.-This epistle was written to set forth grace in contrast to law, and faith in contrast to works. Here for a second time we find the great center of Paul’s doctrinal system: “The just shall live by faith,” with faith now the emphatic word. The epistle is full of contrasts: the flesh and its works, the Spirit and his fruits; circumcision and new creation; the world and the cross. [p. 113] HBS 43.5
