The Bible says that you are wonderful because you are made in the image of God, but that you are flawed because at a space-time point of history man fell. The reformers knew that man was separated from God because of manís revolt against God. But the reformers, and the people who following the Reformation built the culture of Northern Europe, knew that while man is morally guilty before the God who exists, man is not nothing. Modern man tends to think that he is nothing. The reformers knew they were the very opposite of nothing, because they knew they were made in the image of God. Even though they were fallen and, without the nonhumanistic solution of Christ and His substitutionary death, were separated from God and would go to Hell, this still did not mean that they were nothing.
Francis A. Schaeffer, Escape From Reason, Ch. 2
