Duane teaches the importance of cultivating a "Culture of Excellence" within the church and personal life. Excellence should not be confused with perfectionism. Excellence is about doing the best we can with what we have and know, making our work and actions reflect God's nature. 

Drawing from Philippians 1:9-10, Duane explains how love should abound in knowledge and discernment. Excellence is not just about outward actions but also about maintaining an excellent spirit, as seen in Daniel 6:3. Excellence impacts behavior, attitudes, and work ethic. Believers are encouraged to be consistent in everything they do. 

Psalms 8:1 praises the Excellence of God's name, and Psalms 36:7 emphasizes God's excellent loving-kindness. The purpose of Excellence is to carry and reflect God's glory to others, to be a bridge that transports people to God and vice versa.
