- Elisabeth Elliot
Nature does not complete things. She is chaotic. Man must finish, and he does so by making a garden and building a wall.
- Robert Frost
When they have opened a gap in the ... wall of separation between the Garden of the Church and the wildernes of the world, God hath ever ... made his Garden a Wildernesse.
