Scriptural Reference for Imputation

"The cluster of texts that I think are most helpful about imputation would be Philippians 3:7–9, 2 Corinthians 5:21, 1 Corinthians 1:30, the flow of thought from Romans 3:20–4:6, especially 4:4–6. Galatians 2:16 and all of chapter 3. As far as biblical texts, that is where I would go."
