To be righteous means to be someone who practices righteousness, so being imputed with righteous living does not result in righteous living, but rather righteous living is intrinsically part of what it means to have imputed righteousness."for it is not the hearers of the Law who are just before God" The term "hearers" can refer to-
rabbinical usage which had a specialized sense of rabbinical students of the Torah
those who heard the Scriptures read in synagogue
Remember the writers of the NT were Hebrew thinkers writing in Koine Greek. Therefore, word analysis must begin with the Septuagint, not a Greek lexicon.
The term "just" or "justified" (dikē in all its forms) is a crucial term in Paul's theology (cf. Rom. 3:4, 20,24,26,28,30; 4:2,5; 5:1,9; 6:7; 8:30,33). The words "just," "justify," "justification," "right," and "righteousness" are all derived from dikaios. In Hebrew (tsadag, BDB 843) it originally referred to a long straight reed (15 to 20 feet) which was used to measure things, such as walls or fences, for plumb. It came to be used metaphorically of God as the standard of judgment.
In Paul's writings the term had two foci. First, God's own righteousness is given to sinful mankind as a free gift through faith in Christ. This is often called imputed righteousness or forensic righteousness. It refers to one's legal standing before a righteous God. This is the origin of Paul's famous "justification by grace through faith" theme.
Second, God's activity of restoring sinful mankind into His image (cf. Gen. 1:26-27), or to put it another way, to bring about Christlikeness. This verse-like Matt. 7:24; Luke 8:21 and 11:28; John 13:17; James 1:22-23,25-urges believers to be doers not just hearers.
Imputed righteousness (justification) must result in righteous living (sanctification). God forgives and changes sinners! Paul's usage was both legal and ethical.
The New Covenant gives humans a legal standing but also demands a godly lifestyle. It is free, but costly!

The content of a gift can itself be experience of doing something, such as giving someone the opportunity to experience driving a Ferrari for an hour, where that experience intrinsically requires them to do the work of driving it, but where doing that work has not to do with trying to earn the opportunity as a wage. Likewise, the content of God's gift of eternal life is the experience of knowing Him and Jesus (John 17:3) and the gift of God's law is His instructions for how to have that experience, and the same is true for getting to have the gift of experiencing the righteousness of God through obeying His law.
