What does A Christmas Carol show us about redemption?

We are shown that redemption cant only be completed by reflecting your past actions. Although you do need to accept and acknowledge any wrong you have done, you also need to use your actions to make amends. We are shown times of redemption when Scrooge says "that is my name and I fear it may not be pleasant to you". Here we see how he knows and regrets the wrongs he has done.
