Daniel 4:27

How does that insolence and the mighty arrogance of words and the great and terrible flame of the furnace aid Nebuchadnezzar when he is not master of his own soul? And on account of this the blessed Daniel became his counselor, like a good doctor who wishes to heal his hurts. Now he said, "Let my counsel please you and redeem your sins in alms and your unrighteous deeds by pity on the poor. Perhaps he will be patient upon your trespasses." [Daniel 4:27]

Verse 27. "'Wherefore, O king, let my counsel meet with thy favor, and make up for thy sins by deeds of charity, and thine iniquities by showing mercy to the poor. Perhaps God will forgive thy transgressions.'" Since he had previously pronounced the sentence of God, which of course cannot be altered, how could he exhort the king to deeds of charity and acts of mercy towards the poor? This difficulty is easily solved by reference to the example of King Hezekiah, who Isaiah had said was going to die (Isaiah 38:1); and again, to the example of the Ninevites, to whom it was said: "Yet forty days, and Nineveh shall be destroyed" (Jonah 3:4). And yet the sentence of God was changed in response to the prayers of Hezekiah and the city of Nineveh, not by any means because of the ineffectualness of the judgment itself but because of the conversion of those who merited pardon. Morever in Jeremiah God states that He threatens evil for the nation (Jeremiah 18:7-8), but if it does that which is good, He will alter His threats to bestow mercy. Again, He affirms that He directs His promises to the man who does good; and if the same man thereafter works evil, He says that He changes His decision, not with regard to the men themselves, but with regard to their works which have thus changed in character. For after all, God is not angered at men but at their sins; and when no sins inhere in a man, God by no means inflicts a punishment which has been commuted. In other words, let us say that Nebuchadnezzar performed deeds of mercy toward the poor in accordance with Daniel's advice, and for that reason the sentence against him was delayed of execution for twelve months. But because he afterwards while walking about in his palace at Babylon said boastingly: "Is this not the great Babylon which I myself have built up as a home for the king by the might of my power and the glory of my name?" therefore he lost the virtue of his charitableness by reason of the wickedness of his pride. "It may be that God will forgive thy sins." In view of the fact that the blessed Daniel, foreknowing the future as he did, had doubts concerning God's decision, it is very rash on the part of those who boldly promise pardon to sinners. And yet it should be recognized that indulgence was promised to Nebuchadnezzar in return, as long as he wrought good works. Much more, then, is it promised to other men…
