In this post, John Piper challenges preachers to proclaim in such a way as to never nullify the cross. According to Piper no matter your preaching style, there is always a danger to left high yourself rather than the cross.
The Bible never avoids difficult topics; therefore, the preacher has no excuse for avoiding topics considered uncomfortable. In fact, by avoiding seemingly uncomfortable topics you are doing your hearers a great disservice.
According to Jason Corn in this post, “Jesus excerts a gravitational pull on all of Scripture.” His presences in the biblical text is unavoidable. Hence, that means preaching needs to be guided by that central pull.
