Every preacher faces a choice. One can preach stability, promoting the existing spiritual situation of the congregation. This is preaching what the congregation desires to hear: they are doing well and they are headed for salvation. On the other hand, one can decide to preach transformation, promoting a higher level of spirituality for a congregation so it can recognize the need to move closer to the Triune God. Most congregations do not like to hear preaching that tells them to change, making them uncomfortable with the lives they lead. Transformative preaching takes courage and skill. A quick review of the preaching lives of two historical preachers might put this concept into better focus.
