What, then, does it mean to worship God? It is to “glory in His holy name” (Ps. 105:3), that is, to revel adoringly in who He is in his revealed character. But before we can glory in God’s name, we must know it. Hence the propriety of the reading and preaching of the Word of God in public worship, and of biblical meditation in private devotion. These things are not an intrusion into worship; they form the necessary foundation of it.
God must speak to us before we have any liberty to speak to Him. He must disclose to us who He is before we can offer Him what we are in acceptable worship. The worship of God is always a response to the Word of God. Scripture wonderfully directs and enriches our worship.
John Stott, The Contemporary Christian
