In Advent we heighten our anticipation for the ultimate fulfillment of all Old Testament promises, when the wolf will lie down with the lamb, death will be swallowed up, and every tear will be wiped away. Here is a collection of resources to help invigorate Advent season worship services. Categories include service outlines, prayers, visual arts, and sermon series guides, among other topics. The Advent-planning resource is available from the Calvin Institute of Christian Worship.
