"...Within Protestantism there are two very distinct systems of theology. One is a Theology of Glory and the other is a Theology of the Cross.
...The Protestant theology of glory begins with a one-time trip to the Cross of Jesus Christ. The preaching of human sin and divine grace is only directed at the unbeliever in order to "get him saved."
The theology of the Cross is quite different. The preaching of sin and grace or Law and Gospel is not only intended to convert the unbelieving sinner but is intended to produce sanctification in the Christian. The preaching of the Law continues to convict the Christian of sin, leading to contrition, and the Gospel continues to produce faith in the atoning work of Jesus Christ.
A theology of glory separates the Christian life from the Gospel. Once you are saved you are given a list of do’s and don’ts. More often than not, these are "evangelical house rules." If you continue to break the rules or backslide, the solution is the rededication of your life to God or, in some cases, the emotional determination to keep your promises. You wouldn’t go back to the Cross again because you already did that when you got saved. Rather, you rededicate your life, because "once saved, is always saved."
The theology of the Cross never gets you past the Cross. The preaching of the Law is not intended to provide you with a list of do’s and don’ts. Rather the preaching of the Law is intended to drive you back to the Cross through the hearing of the Gospel. As a result of the Gospel, your faith is strengthened. Out of faith, the good works defining the Christian life are produced.
A theology of glory produces people who think they are better than other people. "Getting saved" moves you to a higher level. You are now a better person, a step above those who are not saved. You can think of yourself as a part of the "moral majority" as opposed to the "immoral minority." You share your testimony so that other people will get saved and be a good person just like you are.
Living in a theology of the Cross never makes you any "better" than anyone else. Every day in every way you are not getting better and better. In fact, the preaching of Law and Gospel will not lead you to an awareness of your holiness, but rather to greater awareness of the depth of your sin. As a result, you will develop an ever-increasing faith in and appreciation for the redeeming work of Jesus Christ.
Your witness will focus upon the work of the Cross, not upon your experience of getting saved, sanctified, or becoming more spiritual. You have taken no step toward God or arrived at any higher level of holiness. You don’t talk about your spirituality. You talk about the grace of God in Christ Jesus.
Martin Luther accurately defined sin as man turning in on himself. While a theology of glory continues to turn you to yourself as you measure your growth in holiness against a plethora of spiritual experiences, the theology of the Cross turns you away from yourself. As a result of the conviction of the Law, you forsake your own good works and spiritual experiences and cling to the blood and righteousness of Jesus Christ.
Which is Correct?
Any reading of the New Testament will demonstrate that the systematic theology of the Apostle Paul was a theology of the Cross. His focus was not upon his spirituality but upon the Cross of Christ. He boasted of his weaknesses. He referred to himself as the "chief of sinners" and a "wretched man." As far as he was concerned, his holiness and goodness was manure compared to the righteousness of Christ. For the Apostle, the dynamic of both justification and sanctification was "not I, but Christ."
The Reformation theology that characterizes both Lutheranism and traditional Calvinism is a theology of the Cross. There is no doubt that the theology of glory appeals to natural man. It is a theology of Adam. It is self-focused. It defines "popular Christianity." The reality is, it is not biblical Christianity."
