I ran into a conference talk based on this text. The topic: justification by faith alone. Next, some quotes that stirred my heart:
"Don't trust in what God has worked in you. Trust in Christ alone...his blood and righteousness"
"Your standing as a cherished justified child of God is not based on yourself but in Christ alone..."
"The second Adam never failed"
"Christ...provided my pardon and provided my perfection"
After this talk, this verse now makes sense in my heart:
"For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God" (2 Cor 5:21)
Hallelujah what a Savior!
