"All worship is an intelligent and loving response to the revelation of God, because it is the adoration of his Name. Therefore acceptable worship is impossible without preaching. For preaching is making known the Name of the Lord, and worship is praising the Name of the Lord made known. Far from being an alien intrusion into worship, the reading and preaching of the Word are actually indispensable to it. The two cannot be divorced. Indeed, it is their unnatural divorce which account for the low level of so much contemporary worship.
Our worship is poor because our knowledge of God is poor, and our knowledge of God is poor because our preaching is poor. But when the Word of God is expounded in its fullness, and the congregation begin to glimpse the glory of the living God, they bow down in solemn awe and joyful wonder before his throne. It is preaching which accomplishes this, the proclamation of the Word of God in the power of the Spirit of God."
