Andreas Kostenberger wrote a book on Excellence in scholarship. He argues that a theology of God’s excellence is the foundation of any practical theology of excellence. His thoughts are very helpful and challenging. I encourage you to take a moment and reflect on what he suggests here. A link to the first chapter of the book is included below.
God is the grounds of all true excellence. He is the one who fills any definition of excellence with meaning, and he is the reason why we cannot be content with lackluster mediocrity, halfhearted effort, or substandard scholarship. Excellence starts and ends with God and is first and foremost a hallmark and attribute of God. Without God as our starting point and continual frame of reference, our discussion of excellence would be hopelessly inadequate.
Systematic theologies generally do not list “excellence” as one of God’s attributes. For this reason it may appear at first glance that excellence is not all that important. This conclusion would be premature, however, for excellence can be viewed as an overarching divine attribute that encompasses all the others. Everything God is and does is marked by excellence. Wayne Grudem discusses God’s summary attributes of perfection, blessedness, beauty, and glory as “attributes that summarize his excellence.”
Perfection indicates that “God lacks nothing in his excellence.” Blessedness points to the fact that “God takes pleasure in everything in creation that mirrors his own excellence.” Beauty is a reflection of God’s excellence, and “God’s glory is something that belongs to him alone and is the appropriate outward expression of his own excellence.”6 Understanding excellence as an all-encompassing attribute of God also means that the concept is not exhausted by the word “excellence.” Other descriptions of the uniqueness, greatness, glory, or perfection of God are pertinent as well.
As we have seen, God truly excels in the sense that he stands out from all the rest. His excellence is evident in his unmatched superiority to everyone and everything else. Because God is the proper standard of excellence, we should not measure our achievements by comparing ourselves with others. Our pursuit of excellence should not take place in the kind of competitive spirit according to which only few can participate and where in the end there is only one winner. Since we are all created in God’s image, everyone can be truly excellent. God is unique, and we are made uniquely in his image as distinct creatures. We can each achieve excellence as we are increasingly fulfilling the potential God has built into us.
Since excellence, then, is an all-encompassing attribute of God, and since we are exhorted in Scripture to imitate God, having been made in his likeness, excellence should mark our lives as his children, extending both to who we are (our character and our relationships) and what we do (our work or vocation). Excellence should characterize every thought we have, every paper we write, every relationship we pursue, every assignment we undertake, and every word we speak (see, e.g., Matt. 12:36–37; Eph. 4:29; James 3:1–12). Excellence should describe our lives in their totality and encompass every area of our lives, no matter how large or small.
