Musar zu Jeschijahu 38:17

Likewise Chizkiyahu said: "to peace it is bitterness for me" (Isaiah 38:17) since the Holy One, blessed be He, answered him: "I will defend this city to save it, for My sake and for the sake of My servant David" (Isaiah 37:35). This is as the statement of our sages: "whoever makes his request depend on his own merit, is shown that it was dependent on the merit of others" (Berachot 10b).

And when he contemplates further and pictures in his mind the moment he enters before the great Beit Din of the heavenly host, when he finds himself before the King of kings, the Holy One, blessed be He, who is absolutely pure and holy, in the midst of the assembly of holy ones, mighty servants, strong in power, obeying His word, without any blemish whatsoever, and he stands before them, base, lowly, and petty in and of himself, defiled and polluted due to his deeds. Will he then raise his head? Will he have what to answer? And when they ask him: "where has your mouth gone? Where is the pride and honor which you assumed in your world?"

What will he answer? What will he reply to this rebuke? Behold, certainly if for one moment, a person were to visualize in his mind this truth with a true and strong picture, all of his arrogance would blast off in flight, never to return.
