In Isben's play "The Doll House" what is the miracle that Nora is waiting for?

Nora is waiting for the miracle of her husband stepping up to take the blame for what she has done...... she says, “it’s a wonderful thing to be waiting for a miracle." But her love never takes responsibility and shamelessly puts his own honor before his wife. Not what she'd hoped for...... but an awakening for Nora.
