Roots and Fruits:
Intellectual Influences that Shaped my Christian Calling
Follow my example, as I follow the example of Christ.—1 Corinthians 11:1
I. What is a Christian Calling? (See Os Guinness, The Call)
A. Life direction according to spiritual gifts, opportunities, and strong desires
1. What needs to be done for the Mission of God
2. What one does well
3. What gives one deep joy
B. My calling (Matthew 6:33; 1 Corinthians 10:31)
1. Defend and apply Christianity as objectively true, rationally compelling, and pertinent to all of life (Matthew 22:37-40; 1 Peter 3:15; Jude 3)
2. To do this through teaching, preaching, and writing
3. What this means: teaching at Denver Seminary, adjunct teaching and guest lecturing at secular schools; preaching in local churches; writing academic and popular works: Twelve books; two dozen peer-review academic journal articles; hundreds of articles, book reviews, and letters to the editor in dozens of magazines, journals, and elsewhere.
