Musings on tree sap take us to the gifts of the Magi, whose visit inspires a sense of hope that, one day, all people will worship together.

Part of a Constant Wonder series marking the Christian Advent with daily vignettes that distill the spirit of the season, in keeping with our mission of exploring wonder and awe in all nature, human or wild, vast or small: encounters that move us beyond words.

Guest: Hannah Anderson, author of "Heaven and Nature Sing: 25 Advent Reflections to Bring Joy to the World"
