This series of rhetorical questions are answered by the information concerning justification in the previous verses. God’s righteousness is revealed apart from the law (v. 21). For justification by law is only through the perfect keeping of the law, and all men fail to do so. It is only through faith in Christ Jesus, who is the propitiation for all man’s sins, that any man is justified (v. 25-26).

For this reason, the law of faith excludes boasting. It’s very existence suggests there are no reasons to boast. Justification by the “deeds of the law” would require perfection, yet all have sinned (v. 23). And so, that a man is justified by faith and not by “deeds of the law,” the necessary conclusion is the impartiality of God. The Jews are justified by faith as well as the Gentiles. The Jews who were once under the Law of Moses have no advantage, because justification is not found under that law, but by faith. However, this does not undermine the existence of law. Obedience is still expected, and disobedience is still deserving of punishment. It is this truth that made Jesus’ sacrifice necessary, and justification by faith in Him.
