From what I see in my life. It’s pride. Pride has destroyed more families, relationships, careers and people than all of the lying, stealing and adultery and combined.
How many relationships have been destroyed because people do something wrong, say something wrong or treat people poorly then they dig in their heals and refuse to acknowledge that they are anything less than perfect? How many times have you seen this. Somebody does something wrong, then they blame another person for their decision? Sometimes all that is needed is for someone to say, “You’re right, I probably should not have said that, or done that.” That’s all it would take to save a relationship. Yet pride gets in the way and people place it above family, friends co-workers, everyone. A relationship can recover from almost any trauma. Except pride. Pride is a death sentence.
In my mind, there is no doubt that the devil (if there is one) loves pride.
