The premise of the book is that for many centuries Bible translators have often translated the greek word "doulos" as servant or bond-servant instead of the more accurate translation "slave". This has been primarily to the negative reaction in the western world to the atrocities that occurred in both the English and the American slave trades. In the process of translating such, a major theological flaw has occurred. We have created a system of Christianity that places a lot of sovereignty in the life of the believer. We have looked at the relationship of Christ-follower and Jesus as a partnership. "Jesus has a wonderful plan for your life", "Jesus is for you", and "Jesus wants to do abundant things in your life" are some of the popular notions in today's church. They all miss the point that what Christ calls us too in the gospel is complete allegiance, total surrender, and abandonment of self in order to find the treasure of the gospel - Christ himself. MacArthur does a masterful job of taking the reader back to understanding the Roman system of slavery against the more modern understandings of it. He shows the reader that to accurately understand "doulos" we must look at the perspective of the culture in which the New Testament was written. He explains that while slaves had no inherent rights, many of them also benefited greatly from benevolent masters who took care of them.
While some might think on the surface that the ideas that MacArthur expounds sound restrictive, a closer examination shows that they are the pathway to true biblical freedom. No longer do we need to be bound to a system where Jesus is our "friend" and we "try our best to be like him." Instead, through complete submission to Christ, we discover greater intimacy with him, a pathway to obedience, and release from the systems of this world. I would highly recommend every pastor, church leader, and most Christians to pick up a copy of Slave
