Alive in Christ

Paul is really comparing two things here. He is comparing what I was to what I am now. I was dead, but now I am alive in Christ. Before I came to know Jesus, my sins were unforgiven, but now that I am in Christ, my sins are forgiven. This certainly seems to say to me that all of my sins are forgiven. That would include every sin in my life, whether they are sins of my past or any future sins.
