"Worship must be vital and real in the heart, and worship must rest on a true perception of God. There must be spirit and there must be truth. . . . Truth without emotion produces dead orthodoxy and a church full (or half-full) of artificial admirers . . . . On the other hand, emotion without truth produces empty frenzy and cultivates shallow people who refuse the discipline of rigorous thought. But true worship comes from people who are deeply emotional and who love deep and sound doctrine. Strong affections for God rooted in truth are the bone and marrow of biblical worship."
