Love doesn't just sit there, like a stone, it has to be made, like bread; remade all the time, made new.

This quote is saying that love isn’t something that simply exists on its own; it needs to be actively developed and cultivated. This is like baking bread. In order to get fresh bread, it needs to be remade over and over again. Similarly, love needs to be nurtured and worked on continuously in order to make it stronger and more meaningful.
