'I have learned to be content in whatever state] I am'' (Phil. 4:11) Anyone who lacks true contentment may find it in this book. If not, it will be because that one would not follow the very clear and simple instructions given. The teaching is from the Bible, yet it must be described as unique. Nowhere else will you find such unusual, but Biblically authenticated thoughts: He will teach you that contentment lies in subtraction, not in addition; that the ABC's of Christianity are nothing like what you thought them to be; that there is a mystery of contentment, but that once you have learned the way from Christ's word, you will be able to attain such a depth of contentment as you never before dreamed existed. This is a key book for building up Christian maturity. Christian Contentment, what is it? ''It is a sweet, inward heart thing. It is a work of the Spirit indoors. It is a box of precious ointment, very comforting and useful for troubled hearts in times of troubled conditions.
