Romans 5:19

“For as by one man's disobedience many were made sinners, etc..] Agreeably to this the Jews say f102, that “for the sin of the first man, all that are born of him, µy[çr wyhy, “become wicked”.” This is the sum of what is said in the foregoing verses, that as by Adam's sin all his posterity are made sinners, and so are brought under a sentence of condemnation; in like manner by the obedience of Christ, all his seed are made righteous, and come under a sentence of justification of life: the persons made sinners are said to be “many”, in opposition to the “one man”, by whose disobedience they became so, and because there is an exception of one, even Jesus Christ; and mean all the natural…”

“For, &c.--better, "For as by the one man's disobedience the many were made sinners, even so by the obedience of the One shall the many be made righteous." On this great verse observe: First, By the "obedience" of Christ here is plainly not meant more than what divines call His active obedience, as distinguished from His sufferings and death; it is the entire work of Christ in its obediential character.

Calvin says,” Lest anyone should arrogate to himself innocence, (the apostle) adds, that each one is condemned because he is a sinner.” (The same objection which was stated against a previous quotation from Calvin applies here. The…”

“As by the disobedience of one man many (that is, all men) were constituted sinners - Being then in the loins of their first parent, the common head and representative of them all. So by the obedience of one - By his obedience unto death; by his dying for us. Many - All that believe. Shall be constituted righteous - Justified, pardoned. Romans 5:20”

“as by one: Rom 5:12-14 so by: Isa 53:10-12; Dan 9:24; Co2 5:21; Eph 1:6; Rev 7:9-17 Romans 5:20”
