14 Come then, all of you, my brethren, let us worship and fall down, and weep before the Lord our Maker; let us appoint a public mourning, in our various ages and families, let us raise the voice of supplication; and let this, instead of the cry which He hates, enter into the ears of the Lord of Sabaoth. Let us anticipate His anger by confession; let us desire to see Him appeased, after He was angry. Who knows, he says, if He will turn and repent, and leave a blessing behind Him? This I know certainly, I the sponsor of the loving-kindness of God.
And when He has laid aside that which is unnatural to Him, His anger, He will betake Himself to that which is natural, His mercy. To the one He is forced by us, to the other He is inclined. And if He is forced to strike, surely He will refrain, according to His Nature. Only let us have mercy on ourselves, and open a road for our Father's righteous affections. Let us sow in tears, that we may reap in joy, let us show ourselves men of Nineveh, not of Sodom. Let us amend our wickedness, lest we be consumed with it; let us listen to the preaching of Jonah, lest we be overwhelmed by fire and brimstone, and if we have departed from Sodom let us escape to the mountain, let us flee to Zoar, let us enter it as the sun rises; let us not stay in all the plain, let us not look around us, lest we be frozen into a pillar of salt, a really immortal pillar, to accuse the soul which returns to wickedness.
