"Who is righteous?"

(Getting the hang of this now,... if your new to this blog please start reading from the bottom (1st post, then click on comments below first post as I am attempting this blog in a sequence of basic questions)

Romans 2:13
...For it is not those who hear the law who are righteous in God's sight, but it is those who obey the law who will be declared righteous.

Romans 3:10-12
...There is no-one righteous, not even one; there is no-one who understands, no-one who seeks God. All have turned away, they have together become worthless; there is no-one who does good, not even one.

James 2:10
... For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it.

Romans 3:22
...This righteousness from God comes through faith in Jesus Christ to all who believe. There is no difference, for all have sinned and fall short of the glory of God.... Where, then, is boasting? It is excluded. On what principle? On that of observing the law? No, but on that of faith.

For example? Romans 4:3 ...“Abraham believed God, and it was credited to him as righteousness.”
How do we know if this applies to us?
Romans 4:23 ...“The words, ‘it was credited to him’ were not written for him alone, but also for us, to whom God will credit righteousness - for us who believe in him who raised Jesus our Lord from the dead. He was delivered over to death for our sins and was raised to life for our justification.
