Defenses are the costliest of all the prices which the ego would exact. In them lies madness in a form so grim that hope of sanity seems but to be an idle dream, beyond the possible. The sense of threat the world encourages is so much deeper, and so far beyond the frenzy and intensity of which you can conceive, that you have no idea of all the devastation it has wrought.
You are its slave. You know not what you do, in fear of it. You do not understand how much you have been made to sacrifice, who feel its iron grip upon your heart. You do not realize what you have done to sabotage the holy peace of God by your defensiveness. For you behold the Son of God as but a victim to attack by fantasies, by dreams, and by illusions he has made; yet helpless in their presence, needful only of defense by still more fantasies, and dreams by which illusions of his safety comfort him.
Defenselessness is strength. It testifies to recognition of the Christ in you. Perhaps you will recall the text maintains that choice is always made between Christ's strength and your own weakness, seen apart from Him. Defenselessness can never be attacked, because it recognizes strength so great attack is folly, or a silly game a tired child might play, when he becomes too sleepy to remember what he wants.
Defensiveness is weakness. It proclaims you have denied the Christ and come to fear His Father's anger. What can save you now from your delusion of an angry god, whose fearful image you believe you see at work in all the evils of the world? What but illusions could defend you now, when it is but illusions that you fight?
