This is a good exhortation from Doug Wilson as we prepare to preach the Word tomorrow.
Speaking of Heb 4:12-13, Wilson writes:
“…preachers need to learn to preach as though this is what is happening. First, we must handle the Word like a sword. And secondly, we must learn to handle the Word as though it were alive and has a mind of its own- because it does.” (from the chapter, “Thundering the Word,” in A Primer on Worship and Reformation, p. 41)
