To help children grasp the difficult concept of the Trinity, work with shapes such as triangles and 3-leaf clovers. Provide children with different textures of fabric, cardboard, paper and the like to create three-in-one displays. Encourage them to select one of these materials to portray the Trinity in the shape of a triangle or 3-leaf clover. They can use felt-tip pins, cutout letters or other method to identify Father, Son, and Holy Spirit on their creations. The completed designs will illustrate the three-in-one reality of God.
