How Righteous is used in the Bible!

The New Testament continues the Hebrew Bible's tradition of the ethical 
(1 Thessalonians 2:10) and legal (1 Corinthians 4:4) aspects of righteousness. William Lane Craig argues that we should think of God as the paradigm, the locus, the source of all righteousness.^[10] 

 Matthew's gospel contains the most utterances of the word. In Matthew's account of the baptism encounter Jesus tells the prophet "it is fitting for us to fulfill all righteousness" as Jesus requests that John perform the rite for him. The Sermon of the Mount contains the memorable commandment "Seek ye first the kingdom of God and His righteousness". The Greek word dikaiosune also means justice^[11] and the sole translation using this rendering for Matthew 6:33 is the New English Bible.

Jesus asserts the importance of righteousness by saying in Matthew 5:20, "For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven."
 Jesus also re-affirms the Laws of Moses by saying in Matthew 5:19, "Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven."

However, Paul the Apostle speaks of two ways, at least in theory, to achieve righteousness: through the Law of Moses (or Torah); and through faith in the atonement made possible through the death and resurrection of Jesus Christ (Romans 10:3-13). Some interpret that he repeatedly emphasizes that faith is the only effective way. Reference (Romans 4:5). (Romans 3:21-24).

 For example, just a few verses earlier, he states the Jews did not attain the law of righteousness because they sought it not by faith, but by works (Romans 9:30-33). The New Testament speaks of a salvation founded on God's righteousness, as exemplified throughout the history of salvation narrated in the Old Testament (Romans 9-11). 
Paul writes to the Romans that righteousness comes by faith: "...a righteousness that is by faith from first to last, just as it is written: 
'The righteous will live by faith.'" (Romans 1:17)

In II Cor. 9:9 the New Revised Standard Version has a footnote that the original word has the meaning of 'benevolence' and the Messianic Jewish commentary of David Stern affirms the Jewish practice of 'doing tzedakah' as charity in referring to the Matt. 6 and II Cor. 9 passages.^[12]
 
James 2:14-26 speaks of the relationship between works of righteousness and faith, saying that "faith without works is dead." Righteous acts according to James include works of charity (James 2:15-16) as well as avoiding sins against the Law of Moses (James 2:11-12).

2 Peter 2:7-8 describes Lot as a righteous man.
