For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater: (Isaiah 55:10)
Rain is a gift of God to man. It remains here to accomplish the beneficent purpose for which it was sent. That purpose accomplished, it returns to heaven as vapor, ready to be sent forth again. Thus it is with all things ordained of God, whether in the realm of the material or of the spiritual.
As the rain.
The forces of nature are obedient to Him who created them. Rain serves Him by refreshing the earth and enabling it to bring forth verdure, fragrance, beauty, and food for the joy and well-being of man.
