The line that jumped out at me today was in the section where the White Witch comes to talk to Aslan after Edmund has been rescued. Everyone except Edmund is somewhat afraid of the Witch - horrified by her fierce look. The Witch states that Aslan has a traitor with him.
But Edmund had got past thinking about himself after all he'd been through and after the talk he'd had that morning. He just went on looking at Aslan. It didn't seem to matter what the Witch said.
When I heard that part read - I kept thinking that when Satan accuses us (and he continually does even if just by bringing up past sins from years ago), we need to get past thinking about ourselves and just keep looking at Jesus.
