How do we know perfect righteousness is found in Christ?

In the context of salvation, the Apostle Paul emphasizes that despite his Pharisaical background and his claim of being blameless according to the law, he realized that true righteousness could not be obtained through his efforts. When the law revealed his heart's intent, he understood his need for a savior. Therefore, it is through faith in Christ that we are declared righteous, as He is the only one who perfectly obeyed God's law in thought and deed. His finished work on the cross secures our justification, affirming that our righteousness comes not from ourselves but from Him alone.
