An excellent summary of the experience of conversion

Aimee Milburn said this in the comments to a post by Abigail:

St. Augustine wrote in City of God that there are just two cities, the City of God and the city of man, and they interpenetrate each other. When one has been a citizen of the city of man, and changes to the City of God, there's a whole new way of life and thinking to be learned, like entering the culture of another country.

Great analogy.
