The human need for light and warmth are miraculously met by our planet and solar system. Ben Abbott compares these earthly systems to Christ's divine mission. 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: Ben Abbott, professor of Plant and Wildlife Sciences at BYU
