Having established the great truth that God required real moral goodness, he considers the position of the Jews. Could they not plead special divine favour? Was there no advantage in Judaism? Surely there was, especially in that they possessed the oracles of God. The ways of God were full of blessing in themselves, although that did not change the immutable truths of His nature. And if many among them had been unbelieving, this did not alter the faithfulness of God; and the fact that the unbelief of many did but the more demonstrate the faithfulness of God, who remained the same whatever they might be, took nothing from the claims of righteousness. Unbelievers should be punished according to what they were; it would but magnify the unfailing faithfulness of God, which never failed, however unavailing it might be for the mass of the nation.

If we consider him then thus according to the flesh (that is, in connection with the privileges that descended from him as inheritance for his children) and take our place under him in the line of succession to enjoy those privileges, on what principle does this set us? On the same principle of faith. He would have had something to boast of if he was justified by works; but before God it was not so. For the scriptures say, “Abraham believed God, and it was counted unto him for righteousness. Now to him that worketh is the reward not counted of grace, but of debt. But to him that worketh not, but believeth on him who justifieth the ungodly, his faith is counted for righteousness.” For thereby, in fact, he glorifies God in the way that God desires to be glorified, and according to the revelation He has made of Himself in Christ. ...
