Justification and Imputed Righteousness

"Algo" in the combox recently pointed me to some good videos by R. C. Sproul on the issues of Justification and Imputed righteousness vs. Infused righteousness. These videos are good additions to the list of resources on the doctrine of Justification by Faith alone and more resources, and John Piper's sermons below.
