'Righteousness' in the Bible

Simon Peter, a servant and an apostle of Jesus Christ, to them that have obtained like precious faith with us through the righteousness of God and our Saviour Jesus Christ:

Because by his power he has given us everything necessary for life and righteousness, through the knowledge of him who has been our guide by his glory and virtue;

And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly;

For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.

Seeing then that all these things are coming to such an end, what sort of persons is it right for you to be, in all holy behaviour and righteousness,

Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
