What event do the words of the boy and the innkeeper foreshadow?

The Words of the boy and the innkeeper in the story "A Christmas Carol" by Charles Dickens foreshadow the visit of the three spirits (Past, Present, and Yet to Come) who guide Scrooge on a journey of self-discovery and redemption. The boy's line, "I could do it if I had the time," hints at the limited time Scrooge has to change, while the innkeeper's comment that the spirits have done Scrooge "good" suggests that their visit will ultimately have a positive impact on him.
