The Jesse Tree is named from Isaiah 11:1: "A shoot will spring forth from the stump of Jesse, and a branch out of his roots." It is a way to tell the story of God in the Old Testament, and to connect the Advent Season with the faithfulness of God across 4,000 years of history.

Every day in Advent we hang a symbol on the tree and run through the bible story from creation (sun), the fall (apple) and the flood (rainbow) right up to the birth of Christ (manger scene) with lots in between... The kids love to hang up the decorations and we use them to help them to learn a simple bible overview.
