16 And [shall] not as by one that has sinned [be] the gift? For the judgment [was] of one to condemnation, but the act of favour, of many offences unto justification. 17 For if by the offence of the one death reigned by the one, much rather shall those who receive the abundance of grace, and of the free gift of righteousness, reign in life by the one Jesus Christ:) 18 so then as [it was] by one offence towards all men to condemnation, so by one righteousness towards all men for justification of life. 19 For as indeed by the disobedience of the one man the many have been constituted sinners, so also by the obedience of the one the many will be constituted righteous. 20 But law came in, in order that the offence might abound; but where sin abounded grace has overabounded, 21 in order that, even as sin has reigned in [the power of] death, so also grace might reign through righteousness to eternal life through Jesus Christ our Lord.

Commentary on Romans 5:15-19
(Read Romans 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.
Commentary on Romans 5:20-21
(Read Romans 5:20-21)
By Christ and his righteousness, we have more and greater privileges than we lost by the offence of Adam. The moral law showed that many thoughts, tempers, words, and actions, were sinful, thus transgressions were multiplied. Not making sin to abound the more, but discovering the sinfulness of it, even as the letting in a clearer light into a room, discovers the dust and filth which were there before, but were not seen. The sin of Adam, and the effect of corruption in us, are the abounding of that offence which appeared on the entrance of the law. And the terrors of the law make gospel comforts the more sweet. Thus God the Holy Spirit has, by the blessed apostle, delivered to us a most important truth, full of consolation, suited to our need as sinners. Whatever one may have above another, every man is a sinner against God, stands condemned by the law, and needs pardon. A righteousness that is to justify cannot be made up of a mixture of sin and holiness. There can be no title to an eternal reward without a pure and spotless righteousness: let us look for it, even to the righteousness of Christ.
