رومية ٣:٢٣

For all have sinned : - And consequently are equally helpless and guilty; and, as God is no respecter of persons, all human creatures being equally his offspring, and there being no reason why one should be preferred before another, therefore his endless mercy has embraced All. And come short of the glory of God - και υστερουνται της δοξης του θεου These words have been variously translated. Failed of attaining the glory of God: Have not been able to bring glory to God: Stand in need of the glory, that is, the mercy of God. The simple meaning seems to be this: that all have sinned, and none can enjoy God's glory but they that are holy; consequently both Jews and Gentiles have failed in their endeavors to attain it, as, by the works of any law, no human being can be justified.

for all have sinned--Though men differ greatly in the nature and extent of their sinfulness, there is absolutely no difference between the best and the worst of men, in the fact that "all have sinned," and so underlie the wrath of God. and come short of the glory--or "praise" of God--that is, "have failed to earn His approbation" (compare Joh 12:43, Greek). So the best interpreters.

Where is boasting then?.... There is no room nor reason for it, either in Jews or Gentiles: not in the Jews, who were very apt to boast of their being Abraham's seed; of their circumcision; of their being Israelites; of their having and keeping the law; of God being their God; and of their knowledge of him: nor in the Gentiles, who were ready to boast of their philosophy, wisdom, and learning; of their self-sufficiency, freewill, and of the things they had in their own power. It is excluded; it is shut out of doors; the key is turned upon it; it is not allowed of; it is entirely exploded: by what law? of works? nay; for, that establishes boasting when men seek life, righteousness, and salvation by the works of it, and fancy they shall be able to attain them this way: but by the law of faith: not by a law requiring faith; nor as if the Gospel was a law, a new law, a remedial law, a law of milder terms; but the word "law" here answers to the Hebrew word which signifies any "doctrine" or "instruction", and oftentimes the doctrine of the Gospel, as in Isa 2:3, and here particularly, the doctrine of a sinner's justification by faith in the righteousness of Christ; according to which doctrine the most unlikely persons are justified, even ungodly persons, the worst and vilest of sinners; and that without any consideration of works, by faith only, which is freely given them; and by faith in Christ's righteousness only: so that there is not the least room for boasting in the creature, but all their boasting is in Christ, who is made unto them righteousness, and by whom they are justified.

The apostle, in this chapter, carries on his discourse concerning justification. He had already proved the guilt both of Gentiles and Jews. Now in this chapter, I. He answers some objections that might be made against what he had said about the Jews (Rom 3:1-8). II. He asserts the guilt and corruption of mankind in common, both Jews and Gentiles (Rom 3:9-18). III. He argues thence that justification must needs be by faith, and not by the law, which he gives several reasons for (Rom 3:19 to the end). The many digressions in his writings render his discourse sometimes a little difficult, but his scope is evident.
