11:6 {5} And if by grace, then [is it] {e} no more of works: otherwise grace is no more grace. But if [it be] of works, then is it no more grace: otherwise work is no more work.
(5) Even though all are not elect and chosen, yet let those that are elected remember that they are freely chosen: and let those that stubbornly refuse the grace and free mercy of God impute it to themselves.
(e) This saying demolishes the doctrine of all kinds and manner of works, by which our justifiers of themselves teach that works are either wholly or partly the cause of our justification.
11:6 If by grace, then [is it] no more of works. The salvation of the gospel is by grace. that is, it is the gift which springs from the love of God. If that be true, it is not to be earned by the works of the Jewish law. Paul is very emphatic is showing that the Jewish Christians were saved, not because they deserved it on account of keeping the law blameless, but because they accepted the offered mercy of God.
11:6 And if by grace, then it is no more of works - Whether ceremonial or moral. Else grace is no longer grace - The very nature of grace is lost. And if it be of works, then it is no more grace: else work is no longer work - But the very nature of it is destroyed. There is something so absolutely inconsistent between the being justified by grace, and the being justified by works, that, if you suppose either, you of necessity exclude the other. For what is given to works is the payment of a debt; whereas grace implies an unmerited favour. So that the same benefit cannot, in the very nature of things, be derived from both.
11:1-10 There was a chosen remnant of believing Jews, who had righteousness and life by faith in Jesus Christ. These were kept according to the election of grace. If then this election was of grace, it could not be of works, either performed or foreseen. Every truly good disposition in a fallen creature must be the effect, therefore it cannot be the cause, of the grace of God bestowed on him. Salvation from the first to the last must be either of grace or of debt. These things are so directly contrary to each other that they cannot be blended together. God glorifies his grace by changing the hearts and tempers of the rebellious. How then should they wonder and praise him! The Jewish nation were as in a deep sleep, without knowledge of their danger, or concern about it; having no sense of their need of the Saviour, or of their being upon the borders of eternal ruin. David, having by the Spirit foretold the sufferings of Christ from his own people, the Jews, foretells the dreadful judgments of God upon them for it, Ps 69. This teaches us how to understand other prayers of David against his enemies; they are prophecies of the judgments of God, not expressions of his own anger. Divine curses will work long; and we have our eyes darkened, if we are bowed down in worldly-mindedness.
