How does Psalm 15 relate to the idea of justification for believers?

The requirements laid out in Psalm 15 highlight the impossibility for humans to meet God’s perfect standard on their own. However, through justification, believers are declared righteous in Christ, who fulfilled every aspect of this Psalm. When Jesus walked uprightly and maintained perfect righteousness, He did so as our representative. This means that believers are not only viewed as not guilty but are credited with Christ’s righteousness, fulfilling the very requirements of Psalm 15.
