Do you have that hunger for Him? As John Piper puts it: "If we don't feel strong desires for the manifestation of the glory of God, it is not because you have drunk deeply and are satisfied. It is because we have nibbled so long at the table of the world. Our soul is stuffed with small things, and there is no room for the great." If we are full of what the world offers, then perhaps a fast might express, or even increase, our soul's appetite for God.
