But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. But to him that worketh not - Which was the case with Abraham, for he was called when he was ungodly, i.e. an idolater; and, on his believing, was freely justified: and, as all men have sinned, none can be justified by works; and, therefore, justification, if it take place at all, must take place in behalf of the ungodly, forasmuch as all mankind are such. Now, as Abraham's state and mode in which he was justified, are the plan and rule according to which God purposes to save men; and as his state was ungodly, and the mode of his justification was by faith in the goodness and mercy of God; and this is precisely the state of Jews and Gentiles at present; there can be no other mode of justification than by faith in that Christ who is Abraham's seed, and in whom, according to the promise, all the nations of the earth are to be blessed.
It is necessary to observe here, in order to prevent confusion and misapprehension, that although the verb δικαιοω has a variety of senses in the New Testament, yet here it is to be taken as implying the pardon of sin; receiving a person into the favor of God. See these different acceptations cited in the note on Romans 1:17 (note), and particularly under No. 7. It is also necessary to observe, that our translators render the verb λογιζομαι differently in different parts of this chapter. It is rendered counted, Romans 4:3, Romans 4:5; reckoned, Romans 4:4, Romans 4:9, Romans 4:10; imputed, Romans 4:6, Romans 4:8, Romans 4:11, Romans 4:22-24. Reckoned is probably the best sense in all these places.
