Have you entered into the treasury of the snow? or have you seen the treasury of the hail,
Read Chapter 38
Gregory The Dialogist
37. What else must be understood by the ‘snow’ or ‘hail,’ but the cold and hard hearts of the wicked? For as charity is designated by warmth, so also in Holy Scripture wickedness is wont to be designated by cold. For it is written, As a cistern maketh its water cold, so doth its own wickedness make cold the soul. [Jer. 6, 7] And again, Iniquity shall abound, and the love of many shall wax cold. [Matt. 24, 12] What then can be more fitly understood by the cold of snow, or the hardness of hail, than the life of the wicked, which both waxes cold by torpor, and strikes with the malice of hardness? Whose life the Lord yet tolerates, because He keeps them for the probation of His just ones. Whence also He rightly subjoined, Which I have prepared against the time of the enemy, against the day of battle and war. In order that, when our adversary the devil endeavours to tempt us, he may make use of their habits as his weapons against us. For by them he tortures us in his rage, but unwittingly purges us. For they become scourges to our sins, and when we are smitten by their life, which is such, we are freed from eternal death. Whence it is so ordered, that even the abandoned life of the reprobate benefits the life of the Elect, and that whilst their ruin furthers our interest, it is thus marvellously ordained, in order that even every thing which is lost, may not be lost to the Elect of God.
38. This also can be understood in another way, so as not to differ from the exposition of the former verse, since it seems connected with the words that precede it. For because He had pointed out that either the good can be changed to sin, or the wicked to goodness.
