V. 8, 9. These verses confirm the preceding declaration. The manifestation of the grace of God is the great end of redemption. This is plain, for salvation is entirely of grace. Ye are saved by grace; ye are saved by faith and not by works; and even faith is not of yourselves, it is the gift of God. We have then here a manifold assertion, affirmative and negative, of the gratuitous nature of salvation. It is not only said in general, ‘ye are saved by grace,’ but further that salvation is by faith, i.e. by simply receiving or apprehending the offered blessing. From the very nature of faith, as an act of assent and trust, it excludes the idea of merit. If by faith, it is of grace; if of works, it is of debt; as the apostle argues in Romans 4:4, 5. Faith, therefore, is the mere causa apprehendens, the simple act of accepting, and not the ground on which salvation is bestowed. Not of works. The apostle says works, without qualification or limitation. It is not, therefore, ceremonial, as distinguished from good works; or legal, as distinguished from evangelical or gracious works; but works of all kinds as distinguished from faith, which are excluded. Salvation is in no sense, and in no degree, of works; for to him that worketh the reward is a matter of debt. But salvation is of grace and therefore not of works lest any man should boast. That the guilty should stand before God with self–complacency, and refer his salvation in any measure to his own merit, is so abhorrent to all right feeling that Paul assumes it (Romans 4:2) as an intuitive truth, that no man can boast before God. And to all who have any proper sense of the holiness of God and of the evil of sin, it is an intuition; and therefore a gratuitous salvation, a salvation which excludes with works all ground of boasting, is the only salvation suited to the relation of guilty men to God.
The only point in the interpretation of these verses of any doubt, relates to the second clause. What is said to be the gift of God? Is it salvation, or faith? The words καὶ του̂το only serve to render more prominent the matter referred to. Compare Romans 13:11; 1 Corinthians 6:6; Philippians 1:28; Hebrews 11:12. They may relate to faith(τὸ πιστεύειν) or to the salvation spoken of (σεσωσμένους εἰ̂ναι). Beza, following the fathers, prefers the former reference; Calvin, with most of the modern commentators, the latter. The reasons in favor of the former interpretation are,
