{18} For as by one man's {y} disobedience {z} many were made sinners, so by the obedience of one shall many be made righteous.

(18) The foundation of this whole comparison is this, that these two men are set as two heads or roots, so that out of the one comes sin by nature, and from the other righteousness by grace springs forth upon others.

(y) So then, sin enters not into us only by following the steps of our forefathers, but we receive corruption from him by inheritance.

(z) The word many is contrasted with the words a few.

People's New Testament

5:19 For as by one man's disobedience. By Adam's disobedience, all disobeyed and were counted sinners.

So by the obedience of one. By Jesus' obedience, all are counted obedient, and hence, righteous. That is, all inherited penalty for Adam's sin is blotted out for the whole race. All who have not personal sins are held to be justified. Hence all infants are sinless. The basis of infant baptism is removed. Baptism is for those who have personally sinned.

Wesley's Notes

5:19 As by the disobedience of one man many (that is, all men) were constituted sinners - Being then in the loins of their first parent, the common head and representative of them all. So by the obedience of one - By his obedience unto death; by his dying for us. Many - All that believe. Shall be constituted righteous - Justified, pardoned.

Jamieson-Fausset-Brown Bible Commentary

19. For, &c.-better, "For as by the one man's disobedience the many were made sinners, even so by the obedience of the One shall the many be made righteous." On this great verse observe: First, By the "obedience" of Christ here is plainly not meant more than what divines call His active obedience, as distinguished from His sufferings and death; it is the entire work of Christ in its obediential character. Our Lord Himself represents even His death as His great act of obedience to the Father: "This commandment (that is, to lay down and resume His life) have I received of My Father" (Joh 10:8). Second, The significant word twice rendered made, does not signify to work a change upon a person or thing, but to constitute or ordain, as will be seen from all the places where it is used. Here, accordingly, it is intended to express that judicial act which holds men, in virtue of their connection with Adam, as sinners; and, in connection with Christ, as righteous. Third, The change of tense from the past to the future-"as through Adam we were made sinners, so through Christ we shall be made righteous"-delightfully expresses the enduring character of the act, and of the economy to which such acts belong, in contrast with the for-ever-past ruin of believers in Adam. (See on [2201]Ro 6:5). Fourth, The "all men" of Ro 5:18 and the "many" of Ro 5:19 are the same party, though under a slightly different aspect. In the latter case, the contrast is between the one representative (Adam-Christ) and the many whom he represented; in the former case, it is between the one head (Adam-Christ) and the human race, affected for death and life respectively by the actings of that one. Only in this latter case it is the redeemed family of man that is alone in view; it is humanity as actually lost, but also as actually saved, as ruined and recovered. Such as refuse to fall in with the high purpose of God to constitute His Son a "second Adam," the Head of a new race, and as impenitent and unbelieving finally perish, have no place in this section of the Epistle, whose sole object is to show how God repairs in the second Adam the evil done by the first. (Thus the doctrine of universal restoration has no place here. Thus too the forced interpretation by which the "justification of all" is made to mean a justification merely in possibility and offer to all, and the "justification of the many" to mean the actual justification of as many as believe [Alford, &c.], is completely avoided. And thus the harshness of comparing a whole fallen family with a recovered part is got rid of. However true it be in fact that part of mankind is not saved, this is not the aspect in which the subject is here presented. It is totals that are compared and contrasted; and it is the same total in two successive conditions-namely, the human race as ruined in Adam and recovered in Christ).

Matthew Henry's Concise Commentary

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.
