Romans 5:19

For as through the one man's disobedience the many were made sinners, even so through the obedience of the one shall the many be made righteous. [Romans 5:18 has spoken of the effects; viz. condemnation and justification. This verse proves that these effects must come, for it sets forth the causes, sin and righteousness, which produce them, and shows where and how these causes came to exist, thus showing that Adam and Christ resemble each other in that one is the fountain of evil and the other the fountain of good; for, as the disobedience of one caused many (all) to be constituted sinners who had personally committed no sin, so the obedience of the other (Philippians 2:8) caused the many (all) to be constituted righteous as to Adam's sin (i. e., sufficiently to be resurrected). It is evident that only in verses 16 and 17 does Paul suggest any of those larger results wherein the act of Christ exceeded those of the acts of Adam. It may seem strange to some that, having thus introduced the larger things of Christ, Paul should, in verses 18 and 19, return to those things wherein the acts of each were equal. But this is to be expected, for Paul is describing the resemblance of the two; and of course, where one exceeds the other, the resemblance ceases. It is natural, therefore, that Paul should briefly dismiss these enlargements or "abundances" of Christ which exceed similarity, and return to that precise point, the unity of the many in the one, which constitutes between the two federal heads the relation of type and antitype. It was Paul's design to establish this oneness, "in order that," as Chrysostom observes, "when the Jew says to you, 'How by the well-doing of one, Christ, was the world saved?' you may be able to say to him, 'How by the disobedience of one, Adam, was the world condemned?'"]
