It denotes “a judicial act of administering the law – in this case by declaring a verdict of acquittal, and so excluding all possibility of condemnation.” – J.I. Packer
Who was betrayed and crucified because of our sins, and was raised [from the dead] because of our justification [our acquittal—absolving us of all sin before God]. – Romans 4:25
What happens in our justification —
Nor is the gift [of grace] like that which came through the one who sinned. For on the one hand the judgment [following the sin] resulted from one trespass and brought condemnation, but on the other hand the free gift resulted from many trespasses and brought justification [the release from sin’s penalty for those who believe]. For if by the trespass of the one (Adam), death reigned through the one (Adam), much more surely will those who receive the abundance of grace and the free gift of righteousness reign in [eternal] life through the One, Jesus Christ.
So then as through one trespass [Adam’s sin] there resulted condemnation for all men, even so through one act of righteousness there resulted justification of life to [a]all men. Romans 5:16-18
