We discussed here that God will deal with the proud and haughty. Isaiah makes it clear that, even though it is not obvious to people now, and even though it may seem slow in coming, a specific day of reckoning for the unrepentant proud will come. Proud mankind will think everything is going well, until the tables are instantly turned.
12 For the Lord of hosts will have a day of reckoning
Against everyone who is proud and lofty
And against everyone who is lifted up,
That he may be abased.
