We’re in the spiritual season of Lent and in partnership with Trinity UMC in North Park, San Diego we have a new sermon series called Shaking Foundations. This series explores the story and theology of theologian Paul Tillich in conversation with stories from the Gospel of Luke. Tillich’s big idea was that God is the “ground of being,” the Very One Who Holds All Existence Together. Jesus lived from this ground at his very center and invites us to keep our feet planted here also.
