Our calling as preachers is to proclaim the Bible, plain and simple. We must also deliver God’s Word in an engaging and authentic manner. My conviction is that the Spirit of God and the Word of God come together in the heart and mind of the preacher to produce substantive and compelling sermons that transform the lives of the listeners. A preacher’s head and heart must meet together in the Holy Spirit to produce powerful preaching that informs the mind, inflames the heart, moves the will, and transforms the life. The Word of God is the substance of our message. It is living and active, sharper than any two-edged sword (Heb. 4:12). The Spirit of God is the fire of our message. He ignites us as we prepare it and deliver it, and he ignites our listeners as they hear it.
One way to overcome the apathy of the pew toward preaching is for preachers to return to the days of Jeremiah, when the Word of God was so powerfully shut up in his bones like fire that he couldn’t hold it in (Jer. 20:9)! Come to the pulpit so full of the Word of God and so full of the Spirit of God—unable to hold it in—and you will find that your people cannot wait to take it in! Moody said, “Catch on fire for Jesus, and the world will come to watch you burn.”
