16 And the result of God's gracious gift is very different from the result of that one man's sin. For Adam's sin led to condemnation, but God's free gift leads to our being made right with God, even though we are guilty of many sins. 17 For the sin of this one man, Adam, caused death to rule over many. But even greater is God's wonderful grace and his gift of righteousness, for all who receive it will live in triumph over sin and death through this one man, Jesus Christ. 18 Yes, Adam's one sin brings condemnation for everyone, but Christ's one act of righteousness brings a right relationship with God and new life for everyone. 19 Because one person disobeyed God, many became sinners. But because one other person obeyed God, many will be made righteous. 20 God's law was given so that all people could see how sinful they were. But as people sinned more and more, God's wonderful grace became more abundant. 21 So just as sin ruled over all people and brought them to death, now God's wonderful grace rules instead, giving us right standing with God and resulting in 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.
