Plead the blood? Sins under the blood? (No, taken away!)

What does it mean that Jesus became sin? What are the implications of us becoming God’s righteousness? When do we ask God to forgive us of all our sins? Do we need to “plead the blood” of Jesus? Are our sins “under the blood”? How does Satan masquerade as an angel of light?
