We live by automobiles, by electrical appliances, by various services of government, all of which we consider indispensable to our daily existence. However, should these things be taken from us, we could still survive. This is not true of spiritual bread. We can never have too much of the bread that comes down from heaven. Bread is basic.
Physical starvation is a very real threat to hundreds of millions of people on the earth.
Yet far more people starve spiritually. The greatest threat to spiritual health and life is the seeming apparent limited supply of the Bread of Life. Yet God has provided us with an abundance. In a way, spiritual starvation depends on our spiritual appetite, on the quality of our appetite. To live by Jesus involves our dependence, our daily surrender.
