'...we must understand that the expectation of personal perfection is a romanticism not rooted in Scripture. If I demand perfection from myself, then I will destroy myself. Many Christians vacillate between being permissive in regard to sin toward themselves on the one hand, and demanding perfection from themslves on the other. They end up battered and crushed because they do not live up to their own image of perfectionism.'
Francis Schaeffer, 'The Weakness of God's Servants' in No little people, p.51.
