Jeremiah 14:22

What a state the person is in who has deserted the easy yoke and the light burden of Christ to subject himself once again to the yoke of demons and to bear the burden of the heaviest sin! How can this be after we have known that the heart of those who worship idols is ashes and their life more worthless than clay, and after we have said, "Our ancestors possessed false idols, and none of them can bring rain"?

(Verse 22.) Are there any among the idols of the nations that can make it rain? Or can the heavens themselves give showers? Are you not the Lord our God, whom we have waited for? For you have made all these things. After many and various discourses, he returns to the title of the prophecy, in which it is written: that the word of the Lord came to Jeremiah concerning the words of drought. Therefore, what he says is this: because the idols of demons cannot make it rain, nor can the heavens themselves give their own shower, you, Lord our God, whom we have always waited for, in whom we turn our hopes and desires, give us your rain. For all things are yours; and whatever good exists, without you, to whom it belongs, cannot be given. Let us say this also against the heretics, who cannot bestow the rain of doctrine; and although they promise themselves to be heavens and boast about themselves: The heavens declare the glory of God (Psalm 19:1): yet they cannot give the downpour of doctrine. For God alone is the one who instructs his people and grants different graces to those who await him.

After many and various thoughts, he returns to the prophecy's title, in which it is written, "What the word of the Lord gave to Jeremiah concerning the drought." This is why he says, in effect: "Because the idols of demons are unable to make it rain, and the heavens are unable to give showers in and of themselves, therefore give us rain, O Lord our God, on whom we always wait and toward whom we have turned our hope and devotion. For everything is yours, and whatever is good cannot be given without you, to whom it belongs." Let us speak this word also against the heretics who are unable to grant rain showers of doctrine. Although they prefer themselves to be the heavens and thus glory in themselves, concerning what is written, "the heavens tell forth the glory of God," they are nonetheless incapable of providing rain showers of doctrine. For it is God alone who instructs people and grants a diversity of graces to those who wait on him.
