Don Sweeting has a great post on the relationship between worship and justice–a connection made by the Old Testament prophets, to which American evangelical Christianity seems to be re-awakening. He teases out the implications for worship planning and leading:
Sometimes those who plan our worship are sleepy. The prayers are self-centered. Song texts are all focused on personal concerns. The preaching avoids the issues that concerned the prophets. Our services are safe and predictable. The only time we get aroused is over small stuff (music styles, carpet color) not the bug stuff (justice, mercy and the weightiness of God).
