For all the faults and burdens overconfidence can cause, it can be deemed as the most destructive flaw in the human race. Proverbs 16:18 says, “Pride goes before destruction, a haughty spirit before a fall.” This is where the famous saying “Pride comes before the fall” comes from. The Bible states through this verse that a man who is prideful or overconfident will come to be destroyed and those who are arrogant will fall.
