From A Sermon On Confession: I will give you rain. By St. Antony Of Padua. Translated by Paul Spilsbury

The Lord speaks of the rain of confession in Leviticus:

I will give you rain in due seasons, and the ground shall bring forth its increase: and the trees shall be filled with fruit. The threshing of your harvest shall reach unto the vintage, and the vintage shall reach unto the sowing time; and you shall eat your bread to the full.[Lev 26.3-5]

When the Lord gives the penitent rain, that is, a full confession, he will bring for an increase that is his own, not another’s. This increase is the beginning of good works, which he brings forth by the rain of confession. And the trees shall be filled with fruit. Strong and fruitful, the trees are the minds of penitents, strong with the firm intention of not falling again. They are fertile and full of virtues. The threshing of your harvest, when you afflict your flesh, shall reach unto the vintage, heartfelt joy, and the vintage shall reach unto the sowing time, eternal life, in which we shall eat bread to the full, according to the words: I shall be satisfied when thy glory shall appear [Ps 16.15]. See how much good confession does!
