"The conclusion is clear: it took just one offense to condemn mankind; one act of righteousness declares the same mankind innocent. The disobedience of the one man exhibits humanity as sinners; the obedience of another man exhibits humanity as righteous. TMB"

We see then, that as one act of sin exposed the whole race of men to condemnation, so one act of perfect righteousness presents all men freely acquitted in the sight of God! J.B. Phillips

kathistemi = To cause to be, to set up, to exhibit.

We were not made sinners by our own disobedience; neither were we made righteous by our own obedience.

Consequently, then, as [it was] through the effect of one fall to the side (or: the result of one offense) [coming] into all mankind ([permeating] into all humanity; = [extending] into the whole race) [bringing them] into a commensurate effect of a decision (a corresponding result of a negative evaluation which fell in line with the decision and followed the pattern which divided [us] down), THUS ALSO and in the same way, through one just-effect and the result of one right act which set [all humanity] right and in accord with the Way pointed out (through the result of one act of justice, equity and solidarity; through a single decree creating rightwised relationships; through one effect of rightwising which turns [people] in the right direction) [it comes] into ALL MANKIND (all humanity; all people; = the whole race) [bringing them] into a setting right of Life and a liberating rightwising from Life [including them in covenant community] (or: Life's turning [folks] in the right direction resulting in right relating, equity and justice which is in accord with the Way pointed out; a making of situations and conditions to be right, which pertain to Life; an expressing of fairness and equity, which is LIFE; a rightly directed solidarity coming from Life; a just-acting deliverance having the qualities of life). 19. For you see, JUST AS through the unwillingness to listen, or to pay attention, resulting in disobedience (or: the erroneous hearing leading to disobedience) of the one person THE MANY (= the mass of humanity) were rendered (established; constituted; placed down and made to be) sinners (failures; ones who diverge and miss the target), THUS  in the same way  ALSO through the submissive listening and paying attention resulting in obedience of the One, THE MANY (= the mass of humanity) will continue being rendered set-right folks (placed down and established [to be] just ones; constituted folks who have been rightwised to be people in the Way pointed out; made righteous ones who are guilt-free, fair, equitable, and rightly-turned in the solidarity of covenant relationships). ~Jonathan Mitchell Translation
