Scrooge's changed behaviour leads to his redemption
1. Scrooge's redemption doesn't rely on a religious conversion or him going to church and praying more frequently. Instead, he's redeemed because he changes his behaviour towards other people
2. This is consistent with Dickens's view on religion - he thought that Christianity should be about practical kindness and willingness to help other people
3. By the end of the story, Scrooge is "glowing with his good intentions". It's this kindness and generosity that allows him to change his fate and "sponge away" his name from his neglected gravestone. It's as if he's reborn, and he has a second chance to do things better - he even says, "I'm quite a baby"
