John Cassian : "In those days," we are told, "Hezekiah was sick unto death, and he prayed to the Lord, and the Lord heard him and gave him a sign," that, namely of which we read in the fourth book of the kingdoms, which was given by Isaiah the prophet through the going back of the sun. "But," it says, "he did not respond to the benefits which he had received, for his heart was proud. And wrath was kindled against him and against Judah and Jerusalem. He humbled himself afterwards because his heart had been proud, both he and the inhabitants of Jerusalem, and therefore the wrath of the Lord did not come upon them in the days of Hezekiah." How dangerous, how terrible is the malady of vanity! So much goodness, so many virtues, faith and devotion, great enough to prevail to change nature itself and the laws of the whole world—all destroyed by a single act of pride! The result would have been that all his good deeds would have been forgotten as if they had never existed, and he would at once have been subject to the wrath of the Lord unless he had appeased him by recovering his humility. Thus, he who, at the suggestion of pride, had fallen from so great a height of excellence, could only mount again to the height he had lost by the same steps of humility. — INSTITUTES 11.10
