Raoul Said:
"He works on you in a way that will make you think you're winning when you're really losing. It's the oldest trick in the book -- flattery. Out of pride, we think we can't be fooled, we think that we are defeating the devil. But then you realize it is not the devil but YOUR OWN PRIDE that is the enemy, and that the devil is only working on that.
The devil cannot fool anyone who doesn't want to be fooled. In a sense he is an agent of God because he tests us. I'm not saying he's not genuinely evil, he is, but at the same time God has turned this evil to a purpose. The devil thought he was going to overpower God and instead he became just another part of His plan.
His main consolation is that he has the power to trick humans and make them into fools just like he is. He is not a fool in terms of his intellectual capacity, mind you, only in how he USED this great intellectual capacity. Likewise, humans are foolish when they honor their own minds and can't admit how feeble and blind they are compared to God. Only humility and trust in God and the Church, a knowledge of our own insufficency, can stop us from being fooled. That is the irony. If you admit you're weak, you are safe. If you think you are brilliant, you are doomed."
This is something each and every one here should ponder well.
