Writing and faith

[bookish_dragon]

Something I have been wondering since I saw the Christian writers-thread in the Writing Group-forum on NaNo: does being a Christian mean that you have to write about your faith? One of the adages of writing is 'Write what you know', or 'Write what you care about.' For me, my faith falls squarely in both categories. But does that mean that I have to write about it? Will it make other people doubt my level of commitment to God if I don't mention Him in my work? Would it be considered preachy to even just mention a church standing in the background. let alone write about matters of doctrine and faith?

Or do I worry too much and should I just write and see what comes out?
