Romans 3

 Paul writes of righteousness in conjunction with grace and faith - 

Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.

21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;

22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:

23 For all have sinned, and come short of the glory of God;

24 Being justified freely by his grace through the redemption that is in Christ Jesus:

25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God..."  (Romans 3:20–25)

Faith and grace is demonstrated upon the condition of righteousness.
