Римлянам 11:6

And, &c.--better, "Now if it (the election) be by grace, it is no more of works; for [then] grace becomes no more grace: but if it be of works," &c. (The authority of ancient manuscripts against this latter clause, as superfluous and not originally in the text, though strong, is not sufficient, we think, to justify its exclusion. Such seeming redundancies are not unusual with our apostle). The general position here laid down is of vital importance: That there are but two possible sources of salvation--men's works, and God's grace; and that these are so essentially distinct and opposite, that salvation cannot be of any combination or mixture of both, but must be wholly either of the one or of the other. (See on Rom 4:3, Note 3.)

The apostle, having reconciled that great truth of the rejection of the Jews with the promise made unto the fathers, is, in this chapter, further labouring to mollify the harshness of it, and to reconcile it to the divine goodness in general. It might be said, "Hath God then cast away his people?" The apostles therefore sets himself, in this chapter, to make a reply to this objection, and that two ways: - I. He shows at large what the mercy is that is mixed with this wrath (v. 1-32). II. He infers thence the infinite wisdom and sovereignty of God, with the adoration of which he concludes this chapter and subject (Rom 11:33-36).
