While arguing for sola fide and forensic justification, André Reis (SDA) admits that it is the person of David that is in view by Paul with respect to his quotation of Psa 32, and not a general reference to believers merely as some claim:
Paul’s second witness is David.
Abraham might be mistaken for a moral hero; David cannot. The man after God’s
own heart carried adultery and murder on his record, and it is to him that Paul
applies Psalm 32: “Blessed are those whose lawless deeds are forgiven, and
whose sins are covered; blessed is the man against whom the Lord will not count
his sin” (Romans 4:7-8). Paul introduces the psalm as describing “the blessing
of the one to whom God counts righteousness apart from works” (Romans 4:6), and
the psalm nowhere mentions works. When God credits righteousness to a person
and when he does not count that person’s sin, he does one and the same thing:
he acquits him. This acquittal first changes the person’s standing before God,
and only afterward does God change anything in the person himself. (André Reis,
The Apostasy: The Faith Once Delivered and the Church That Left It [The
Sola Collective, 2026], 281)

example of a person who was (re)justified, see:
