I love building our home library. I enjoy going to used book sales and buying anything I think might be useful or interesting. Some time ago, I picked up a science textbook by a Christian publisher and often used by homeschoolers who take a more traditional approach to homeschooling. While I'm not homeschooling primarily for religious reasons and am not a "Christian," I am a Christian and have no problem appreciating the wonder of Creation and giving thanks to God.
Thus, I don't mind when I glance through the text and it claims all sorts of scientific processes, such as the water cycle, are based on God's plan for the world. While the book mentions God frequently, it does not mention Him on every page or with regard to every topic discussed. Though I did wonder to my husband that I could not find the chapter on Evolution.
Then we started to try to think up tag lines for the book -- to go along with what they had already written, that is, acknowledging God's role in everything. I tried "gravity -- because God wants it that way." My husband topped me with:
Gravity -- because God doesn't want your junk floating up to heaven.
