This is very, very reassuring:
There is no need to fear evil. There is every need to understand what it does, how it operates in the world, what it draws upon to sustain itself. We must not shrink from the knowledge of the evilness of evil. Over and over we must know that the real target of evil is not destruction of the body, the reduction to rubble of cities; the real target of evil is to corrupt the spirit of humankind and to give to our soul the contagion of inner disintegration.
When this happens, there is nothing left, the very citadel of humanity is captured and laid waste. Therefore the evil in the world around us must not be allowed to move from without to within. This would be to be overcome by evil.
To drink in the beauty that is within reach, to clothe one’s life with simple deeds of kindness, to keep alive a sensitiveness to the movement of the spirit of God in the quietness of the human heart and in the workings of the human mind - this is always the ultimate answer to the great deception.
