(Rom 5:17) “For if by one man’s offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.)” Compare “the gift of righteousness” to the previous verse, “free gift….unto justification”. Justification means to declare judiciously: “he has not broken the law”, thus “righteous”. Jesus’ righteousness through faith is imputed to (placed upon) me in salvation. What could you or I possibly add to that?
