Knowing there's one thing I still haven't told you: I now believe, by the way, that miracles can happen.

The line frames a late, intimate confession: the speaker admits to having withheld something essential and then offers a change in worldview—belief in miracles. In Sparks’s romantic fiction, “miracles” typically functions less as a claim about the supernatural than as a metaphor for improbable emotional redemption: love arriving against odds, forgiveness, survival, or a second chance that feels undeserved. The phrasing “by the way” softens the declaration, suggesting vulnerability and an attempt to appear casual while revealing something profound. The quote’s power lies in its pivot from secrecy to faith, implying that a relationship or experience has transformed skepticism into hope.
