Billy Sunday

A revival does two things. First, it returns the Church from her backsliding and second, it causes the conversion of men and women; and it always includes the conviction of sin on the part of the Church. What a spell the devil seems to cast over the Church today!

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
