When people ask me to describe my preaching style/emphasis I generally say Text-driven, doxological exposition.
In other words, the primary goal of many/most of my sermons is 'wonder, love, and praise.' In this regard the Reformers were right when they suggested that the pastor-teacher is the main 'worship leader' on the Lord's Day.
For pastors I think it would be helpful to rephrase Packer's quote this way, "Any preaching that does not lead to doxology and worship, is at a fundamental level, a flawed sermon."
