"The theme is the duty of fulfilling the commands of Christ.

(1) This obedience is the true confession of Christ, answering to the greatness of His salvation; mainly in chaps. i.-iv.
(2) Thus the Christian shows his opposition to the world; chaps. v.-viii.
(3) This obedience will be rewarded in the future world; chaps. ix.-xvii.
(4) The conclusion: the preacher’s confession (xviii.), justification of his exhortation (xix.); concluding word of consolation, with doxology (xx.). But the treatment is not strictly logical, nor are the parts clearly distinguished.
The theology shows no traces of heresy, nor does it sharply oppose any false doctrinal views. It lacks the dogmatic precision of a later age, but emphasizes rigid views of the relation of the sexes. “Repentance and good works seem to be the main articles of its creed. Of regeneration there seems to be no definite idea: to be called is the same as to be saved. The Church is pre-existent; the kingdom of God is in the future; no worth is left to this world or to the life in it. The principal argument urged in favor of standing firm in faith is the good issue of it in the next life” (C. J. H. Ropes).
