Throughout the Scriptures, bread serves as a symbol of food in general, or what we need to live—the staff of life. In the Middle East, bread symbolizes life itself (or that which sustains life). Bread, because of its rich source of B vitamins, helps to produce serotonin, regulating our moods, making our hearts glad. Similarly, our spiritual taste buds have been hardwired to crave spiritual contact with God Almighty. Some scientists have referred to this universal craving as the God gene, a built-in desire to believe in something. The only way this spiritual hunger can be satisfied is by the Bread of Life (John 6:47-51). If we try to satisfy this craving through any other means, such as false religion, idolatry, food, sports, entertainment, technology, fashion, money, travel, etc., we will be left unsatisfied and disillusioned. The more we taste the heavenly Bread, the more aware we will become of our spiritual hunger, and the more we will try to satisfy this craving with legitimate spiritual manna—Jesus Christ, the Bread of Life. If we hunger and thirst for righteousness, our craving will be satisfied.
