Barth: Freedom and Evil

"And creaturely freedom means, finally that there is a contigency of what is, a specific existence of the creature; and this specific existence, at any rate of the human creature, means freedom to decide, ability to act one way or another. But his freedom can only be the freedom appropriate to the creature, which possesses its reality not of itself, and which has its nature in time and space... it is limited by the existence of its fellow creatures, and on the other hand by the sovereignty of God. For if we are free, it is only because our Creator is the infinitely free. All human freedom is but an imperfect mirroring of the divine freedom."

"The creature is threatened by the possibliity of nothingness and of destruction, which is excluded by God--and only by God... I am speaking here now of this, in order to make it clear that this whole realm that we term evil--death, sin, the Devil and hell is not God's creation, but rather what was excluded by God's creation, that to which God has said 'No'... What is not good God did not make; it has no creaturely existence. But if being is to be ascribed to it at all, and we would rather not say that is is non-existent, then it is only the power of the being which arises out of the weight of the divine 'No'."
