Our Oneness in Christ is a book about our individual roles in pursuing Christian unity.

Have you ever wondered why so many of God's promises only seem to work occasionally? Or why sickness, both physical and mental, seems to be more prevalent among Christians than it is in the world? Or why all of the efforts at unifying Church organizations have not resulted in more visible unity among believers on the street? A recently released book, Our Oneness in Christ by Ian Johnson and Lauston Stephens,  provides at least one of the major answers to all of these questions: The Church has become too individualistic. God's promises are made to the Body of Christ, and only function properly in our individual lives when that Body is healthy—that is, when we are each individually living out our oneness. Conversely, when the whole Body is sick and weak from disunity, each of its members shares in its sickness and weakness. True Christian unity, manifested in our lives individually, is the key to the manifestation of many of God's promises.

This book starts by establishing that all believers in Christ are already, in fact, one with each other in Christ. This leaves us with the challenge, not of creating unity where it does not exist, but of living consistently with the oneness that already exists.

The first section then explains why living consistently with our oneness is important, including God's commands and expectations, the benefits of living in oneness and the hazards of living contrary to the truth. Part two explains what oneness is and is not, including the concepts that oneness is a harmony of diverse believers each doing their own part, not unison, unanimity or strict conformity to the same mold. Christian unity is not conformity in the externals of faith and practice. The third section deals with practical barriers to living in oneness—selfishness, misunderstandings, heresy, and incorrect understanding of the origin of the organizational divisions in the universal Church—and suggests how to overcome them. The focus of the book is how each of us individually may live out the oneness of the Body and contribute to its health and strength.
