Only at the cross of Christ does man see fully what it is that separates him from God; yet it is here alone that he perceives that he is no longer separated from God. Nowhere else does the inviolable holiness of God, the impossibility of overlooking the guilt of man stand out more plainly; but nowhere else does the limitless mercy of God, which utterly transcends all human standards, stand out more clearly and plainly.

—Emil Brunner
