Is everything human alien to Christians? Many answer this question in the affirmative and live as if they are striving to overcome not only sin, but also human nature. At the heart of this misconception is the belief that spirituality should have nothing to do with the manifestations of human nature. The purpose of this book is to establish a healthy realism in the view of Christian life and to turn the eyes of readers to the most perfect of people – Jesus Christ, because conformity to this image is the highest calling of everyone.
