Did I read accurately that you believe the sin remains it is just covered until some future point?

No, I don't believe that. It is what I know to be Luther's formula, not the removal of sin through Justification, but rather a covering of sin to render it somewhat "non-existent" . Please correct me if I am wrong on that.

If Luther taught that, it is he who is/was wrong. Thank you for correcting my faulty recollection. Luther was a catholic priest, wasn’t he? He retained a few errors when he split from catholicism. But he did get ‘by faith alone in Christ alone’ right.
