From the very beginning of time, human beings have celebrated divine visitations by speaking, writing, singing, drawing, and dancing them. We cannot tell of God's presence in our souls. We create, we build, we choreograph; we play music, paint paintings, or write poetry to communicate this divine presence. For the essential place, the point within us penetrated by the Spirit, is our creative soul. The Creator Spirit seeks out our creativity. Fire begets fire.
Joy is the perception of beauty, unlike happiness, which is because of something. Joy is singing of the heart, a feeling of praise.
