Summary: My word, like rain, accomplishes its purpose on Earth, providing what is needed and fulfilling my will.
Thus says the LORD:
Just as from the heavens the rain and snow come down and do not return there till they have watered the earth, making it fertile and fruitful, giving seed to the one who sows and bread to the one who eats, so shall my word be that goes forth from my mouth; my word shall not return to me void, but shall do my will, achieving the end for which I sent it.
