Jesus Christ and His apostles teach repeatedly in the New Testament that there are only two possible ways to live. The first is described such as "walking in the Spirit" and many other similar phrases. The second is described as "walking in the flesh" and also with other similar descriptions. The Teaching of the New Testament makes it plain that the focus of a believer determines which of these two ways of living that they will experience. This book defines and illustrates from the New Testament what spiritual focus is and how to accomplish it.
