"We are God's children. As such, the family business could be said to include creation, forgiveness, love, mercy, justice, righteousness, peace, joy, feeding the hungry, healing the sick, comforting the sorrowing, setting the lost on the right path, and freeing the slave or prisoner (at least, the emotionally or spiritually imprisoned...). Any other business you'd like to add?
And how exactly are we called to do the above through our writing? I mainly feel called to write to the secular world, comforting the grieving, giving practical help for every-day living, and calling my reader's attention to the wonder and awe that surrounds us every day. Sometimes I explicitly mention God, sometimes not, but everything I write is (or is meant to be, to the best of my ability) from a Christian worldview.
How are you called to do the above and through what?"
I had a very moving night years ago in which I was shown vividly by God (and I wrote this down, so when I figure out where I put it, I can post it) that I am to use my pen as my tool to reach the world. I have no doubt that it truly can be done. That doesn't mean one person is to do everything on their own. None of us would appreciate that anyway, would we? We ALL want to write and be used by God. We all make our little chinks into the seemingly immovable block of the secular world, and God can allow major things to occur here and there as He sees fit.
I am going to include God in everything I write, with the intent of it being published. If nothing else, I will be obedient and loving to include Him. And otherwise, how would He be compelled to use me in any major way if I know I can include him or not include Him and I decide not to?
Some personal specifics to answer your question: Well, one I choose not to reveal until the books come out because it would give away too much! But others are that the song lyrics I wrote are directly about God though written in a way that anyone could be attracted to them and listening to them, not just to be sold to a Christian audience. The poetry collection I started are intended to be for women who are being abused or otherwise oppressed. They are written, and wow was this hard for me because I love words!, for the 'average Jane' who may not be a reader even, let alone someone who would ever spend time with deep poetry. They are written with just enough poetry and mystery to make them interesting, but in simple enough words to be read by any hurting woman. Um...a short story I am working on has an Amish man as the main character. I'm working on a novel that will involve Catholic monks. These are sort of 'segways' into providing a Christian message and putting Christianity in a beautiful light for others. And the Christmas cards I am working on are actually small versions of paintings that will also have a Christian message.
