5:21 That as sin hath reigned. Hence, with this gracious gospel of mercy for every penitent believer, even as sin once reigned and caused universal death,
so might grace reign. All might accept the gospel, and enjoy the divine favor, and thus secure eternal life through Jesus Christ. The scope of God's plan of salvation is wide enough for all. If there are those who are unsaved, it is because they will not come to Christ that they might have life.
5:21 That as sin had reigned - so grace also might reign - Which could not reign before the fall; before man had sinned. Through righteousness to eternal life by Jesus Christ our Lord - Here is pointed out the source of all our blessings, the rich and free grace of God. The meritorious cause; not any works of righteousness of man, but the alone merits of our Lord Jesus Christ. The effect or end of all; not only pardon, but life; divine life, leading to glory.
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.
