I am the Bread of Life (John 6:35).
Jesus is the eternal and effective satisfaction of the human soul. Human nature is hungry for a sense of inner repletion, fullness, and contentment. Nothing physical, experiential, emotional, aesthetic, or intellectual can meet that constant yearning.
The world has no answer to our fundamental human desire. Even our fondest desires meet with disappointment and our dearest pursuits. All our appetites are fed with the bread that eventually spoils. Without the sustenance and satisfaction that comes from heaven, embodied in Jesus Christ, the world itself becomes a veritable desert... and existence a wilderness.
