Amazingly, the king succumbed to pride despite having been forewarned of this very thing—and its dire consequences. We are to warn the lost of the consequences of their sin and plead with them to submit to God, but many will tragically reject our pleas.
To strip a man of his pride, show him the requirements of God’s holy Law. It reveals that he has the heart of a beast (v. 16) and brings him to a point of understanding that the Most High rules in the kingdom of men and gives it to whomever He chooses (v. 32). Like the prodigal son of Jesus’ parable, when the sinner sees his sinfulness in the bright light of God’s Law, he sees that his desire is for pig food and he comes to his senses (vv. 34–37).
Daniel 4:30 The king spoke, saying, “Is not this great Babylon, that I have built for a royal dwelling by my mighty power and for the honor of my majesty?” 31While the word was still in the king’s mouth, a voice fell from heaven: “King Nebuchadnezzar, to you it is spoken: the kingdom has departed from you! 32And they shall drive you from men, and your dwelling shall be with the beasts of the field. They shall make you eat grass like oxen; and seven times shall pass over you, until you know that the Most High rules in the kingdom of men, and gives it to whomever He chooses.” 33That very hour the word was fulfilled concerning Nebuchadnezzar; he was driven from men and ate grass like oxen; his body was wet with the dew of heaven till his hair had grown like eagles’ feathers and his nails like birds’ claws.
