In preparing to preach from John 4 this Sunday I revisited Clowney's chapter on worship in his great book, The Church. He argues that it's the glory of God draws us to worship, and says,
It is not just the transcendent power, wisdom and righteousness of God that demands our worship, but, above all, his love and mercy. The adoring church hymns praises that even angels cannot sing, for only the church has known the divine love that bore the doom of lost sinners and gave them sonship with the Beloved. The height of redemption towers over its depth:
And we, who with unveiled faces all reflect the Lord's glory, are being transformed into his likeness with ever-increasing glory, which comes from the Lord, who is Spirit (2 Cor. 3:18).
The Glory of the Lord that draws our praise becomes a blessing that increasingly transforms our existence, and that will finally make us like Christ.
