For the 2023 Advent season, we're exploring a few of the ways that the birth story of Jesus—and the Incarnation itself—overlap with themes of humbleness. The Christmas carol Go, Tell It on the Mountain reminds us that "Our humble Christ was born." How do these themes of humbleness and humility make their way into our lives today. The fourth and final message in the series looks at how both Zechariah and Mary are invited to step into mystery in Luke chapter 1—two similar scenarios, two very different people, and two entirely different (immediate) outcomes!
