Preaching does not come after worship in the order of the service. Preaching is worship. The preacher worships-exults-over the word, trying his best to draw you into a worshipful response by the power of the Holy Spirit.
My job is not simply to see truth and show it to you. (The devil could do that for his own devious reasons.) My job is to see the glory of the truth and to savor it and exult over it as I explain it to you and apply it for you. That’s one of the differences between a sermon and a lecture.
