We see that God’s winged creatures, which number in millions and millions, eat grain, but there is an unsolved mystery in this, for when the farmer gathers his cultivated crops he does not leave even a single grain. There is no special cultivation for these winged creatures. Where, then, do these birds eat? The law is that when the flock of birds comes down to the earth nature creates the grain there. If the food supply system for birds were based on the farmer, then all the birds would have died of hunger.
