16 And the free gift is not like the effect of the one man's sin. For the judgment following one trespass brought condemnation, but the free gift following many trespasses brings justification. 17 If, because of the one man's trespass, death exercised dominion through that one, much more surely will those who receive the abundance of grace and the free gift of righteousness exercise dominion in life through the one man, Jesus Christ. 18 Therefore just as one man's trespass led to condemnation for all, so one man's act of righteousness leads to justification and life for all. 19 For just as by the one man's disobedience the many were made sinners, so by the one man's obedience the many will be made righteous. 20 But law came in, with the result that the trespass multiplied; but where sin increased, grace abounded all the more, 21 so that, just as sin exercised dominion in death, so grace might also exercise dominion through justification leading 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.
