18 So, then, as through one offence to all men [it is] to condemnation, so also through one declaration of `Righteous' [it is] to all men to justification of life;

Romans 5:18 Meaning and Commentary

Romans 5:18

Therefore as by the offence of one
Or by one offence, as before, the guilt of which is imputed to, and

[judgment came] upon all men to condemnation;
which word is used in a legal sense, and intends condemnation to eternal death, as appears from the antithesis in the text; for if "justification of life", means an adjudging to eternal life, as it certainly does, the judgment or guilt, which is unto condemnation, must design a condemnation to eternal death, the just wages of sin: and this sentence of condemnation comes upon all men, all the sons of Adam without exception, even upon the elect of God themselves; though it is not executed upon them, but on their surety, whereby they are delivered from it:

even so by the righteousness of one, [the free gift] came upon all
men to justification of life;
the righteousness of Christ being freely imputed without works, as it is to all the men that belong to the second Adam, to all his seed and offspring, is their justification of life, or what adjudges and entitles them to eternal life. The sentence of justification was conceived in the mind of God from eternity, when his elect were ordained unto eternal life, on the foot of his Son's righteousness; this passed on Christ at his resurrection from the dead, and on all his people as considered in him, when they, in consequence of it, were quickened together with him; and this passes upon the conscience of a sinner at believing, when he may, as he should, reckon himself alive unto God, and is what gives him a right and title to everlasting life and glory.

Romans 5:18 In-Context

16 and not as through one who did sin [is] the free gift, for the judgment indeed [is] of one to condemnation, but the gift [is] of many offences to a declaration of `Righteous,'
17 for if by the offence of the one the death did reign through the one, much more those, who the abundance of the grace and of the free gift of the righteousness are receiving, in life shall reign through the one -- Jesus Christ.
18 So, then, as through one offence to all men [it is] to condemnation, so also through one declaration of `Righteous' [it is] to all men to justification of life;
19 for as through the disobedience of the one man, the many were constituted sinners: so also through the obedience of the one, shall the many be constituted righteous.
20 And law came in, that the offence might abound, and where the sin did abound, the grace did overabound,
