Righteousness
Righteousness is one of the most common biblical concepts. It can describe human character (both approvingly of good character, and ironically of self-righteousness), the actions of people who follow God’s commandments, God's ways generally, and Christians after the Final Judgment.
The differences between righteous character, righteous deeds, and righteous legal standing can be seen in the fact that inspired Scripture calls certain people righteous in mundane character [Matt 1:19], says their deeds are righteous if done by following The Law [Luke 1:6] or The Holy Spirit [Luke 2:25], but then says "Not one is righteous" in legal standing [Rom 3:10–12].
Some relevant data points are below. Most notably, Jesus is The Righteous One whom The Father promised to crush in order to justify the many by bearing their sin [Isa 53:11], and whom both Peter and Stephen explicitly identify as Jesus [Acts 3:18 and 7:52, respectively]. It was in this way that Jeremiah, prophesying from God, said that Jesus would be known as "Yahweh Our Righteousness."
