The Bible definition of righteousness doesn’t mean right living; right living is a result of righteousness. You can’t live right until you’re righteous. Thus, righteousness, essentially, is a nature; the nature of God that produces in a human person, the rightness of God.
“Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.” 2 Corinthians 5:17
The man who’s born again is a completely new species, one that never existed before. He has only one nature, which is the divine nature—the nature of righteousness.
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 (Romans5:17).
Now that you’re born again, the life and nature of God has completely supplanted the human life and nature with which you were born by your biological parents.
