'Righteousness' in the Bible

Simeon Peter, a slave and apostle of Jesus Christ, to those who have obtained a faith equal in value to ours by the righteousness of our God and Savior Jesus Christ.

and did not spare the ancient world, but preserved Noah, a proclaimer of righteousness, {and seven others} [when he] brought a flood on the world of the ungodly,

For it would have been better for them not to have known the way of righteousness than having known [it], to turn back from the holy commandment that had been delivered to them.

But according to his promise, we are waiting for new heavens and a new earth in which righteousness resides.
