How does Janette Oke use imagery in Love Finds a Home?

Imagery:

"But after three years the bed seemed reluctant to mold to her unfamiliar form, and tired as she was, the clock downstairs had chimed twice before Belinda was finally able to forget the events of the day and settle down to sleep."

"Belinda stood looking down into the empty fireplace. Ashes, she thought. Only ashes where once there was a warm and living flame. It's rather symbolic. Oh, I miss her."
