I came across this very interesting reflection on worship by Peter Leithart a fascinating theologian and the pastor of Trinity Reformed Church in Idaho. How should such an understanding of the service of God to us influence the shape of our services?

"In the first instance, though, worship is not our service to God but the Lord's service to us. We assemble here because we believe He will do what He has promised. What has he promised to do in our worship? He calls us together promising to cleanse us from our sins, speak to us in His word, hear our prayers and praises, feed us at his table, and send us out into the world under his blessing. We trust that God is in fact renewing covenant with us so that we may live each day in communion with him and with one another. Because we trust His promises, we come together expectantly looking to our Triune God to work on and in us that we might work for Him."
