Many first chapters may be rather lengthy. However, many current Christain novels have very short chapters. I have a novel in which I took that route. Is it possible to submit more than one very short chapter? Perhaps a maximum word count could be an alternative to just a first chapter.

things are gone." C.S. Lewis
“The chief purpose of life … is to increase according to our capacity our knowledge of God by all the means we have, and to be moved by it to praise and thanks. To do as we say in the Gloria in Excelsis ... We praise you, we call you holy, we worship you, we proclaim your glory, we thank you for the greatness of your splendor.” J.R.R. Tolkien
