(16) The judgment was by one.--The judgment, verdict, or sentence from a single case ends in, or in other words takes the form of, condemnation; whereas, on the other hand, the free gift, starting from or prompted by many sins, ends in, takes the form of, justification. In the former of these cases the verdict is "Guilty," while in the other case it (or, rather, the free act of grace which takes its place) is a verdict of acquittal.

5:15-19 Through one man's offence, all mankind are exposed to eternal condemnation. But the grace and mercy of God, and the free gift of righteousness and salvation, are through Jesus Christ, as man: yet the Lord from heaven has brought the multitude of believers into a more safe and exalted state than that from which they fell in Adam. This free gift did not place them anew in a state of trial, but fixed them in a state of justification, as Adam would have been placed, had he stood. Notwithstanding the differences, there is a striking similarity. As by the offence of one, sin and death prevailed to the condemnation of all men, so by the righteousness of one, grace prevailed to the justification of all related to Christ by faith. Through the grace of God, the gift by grace has abounded to many through Christ; yet multitudes choose to remain under the dominion of sin and death, rather than to apply for the blessings of the reign of grace. But Christ will in nowise cast out any who are willing to come to him.And not as it was by one that sinned, so is the gift,.... The apostle goes on with the dissimilitude between the effects of Adam's sin, and Christ's righteousness:

for the judgment was by one to condemnation; by "judgment" is meant, not the judgment of God, or the judiciary sentence pronounced by God on Adam and his posterity for sin; but the guilt of the one man's sin, which is imputed to all men to condemnation, on account of which the sentence of condemnation passed on all men; the law transgressed, became a ministration of condemnation to them:

but the free gift is of many offences unto justification; the righteousness of Christ, which stands opposed to the guilt of Adam's sin, being imputed to all his offspring, is to the justification of them; and that not only from the guilt of that particular offence, but from many other offences, even all their actual sins and transgressions, of every sort; which is another instance of the exuberance, or abounding of the grace of God, in the righteousness of Christ, not only over the sin of the one man, but also over the sins of many, even all the elect of God; for the last clause may be also thus rendered, "the free gift is of the offences of many, unto justification".
