For in it the righteousness of God is revealed from faith for faith, as it is written, “The righteous shall live by faith." For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth.
"The wrath of God" stands in obvious antithesis to the "righteousness of God" in verse 17. This fact of antithesis shoes unmistakeably, if any confirmation were needed, that "the righteousness of God" (vs. 17) is not the attribute of justice but the righteousness provided in the gospel to meet the need of which that wrath of God is the manifestation. The justice of God being retributive in reference to sin would not be the provision for escape from wrath. (Murray, John.
