When we speak of the centrality of the gospel we refer to the fact that every aspect of our salvation stems from the gospel. We mean that the gospel is truly the power of God for salvation in that it is through the gospel we are called, regenerated, converted, sanctified, and finally glorified. We mean that Jesus Christ, God come in the flesh, as he lived, died and rose again, gave meaning to all history and human existence. We mean that the gospel is the only means we have of beginning, continuing, and persevering in the Christian life . . . . When we approach sanctification as attainable by any means other than the gospel of Christ–the same gospel by which we are converted–we have departed from the teaching of the New Testament.
