In his book, He is Not Silent, Al Mohler offers a no-holds barred chapter on postmodernity and preaching. After listing a series of negative observations of the postmodern “mood” (and probably failing to recognize the positive opportunities now presented to us as preachers), he presents a series of principles for proper proclamation in a postmodern culture. He earths his thoughts in Acts 17:
1. Christian proclamation in a postmodern culture begins in a provoked spirit (v16)
2. Christian proclamation in a postmodern culture is focused on Gospel proclamation (v17)
3. Christian proclamation in a postmodern culture assumes a context of spiritual confusion (vv18-21)
4. Christian proclamation in a postmodern cultureis directed to a spiritual hunger. (vv22-23)
5. Christian proclamation in a postmodern culture begins with the fundamental issue of God’s nature, character, power, and authority. (vv24-28)
6. Christian proclamation in a postmodern culture confronts error. (v29)
7. Christian proclamation in a postmodern culture affirms the totality of God’s saving purpose. (vv30-31)
Principles worth pondering.
Biblical Preaching 
Good food for thought in any preaching environment.
These ques shouldn’t be exclusively thought of in terms of PoMo culture. Some may be accentuated in these times, but not only limited to now.
