Verse 1 particularly caught my eye.
Guard your steps when you go to the house of God. To draw near to listen is better than to offer the sacrifice of fools, for they do not know that they are doing evil. (ESV)Consulting various commentaries confirmed my hunch that this verse supports the primacy of listening to the faithful preaching of God's Word (with an intent to obey it) over ritualistic sacrifice. Applied to present-day evangelical worship services, this verse encourages keeping sermons, not singing, as the focal point.
Singing, confession and prayer still hold important places in corporate worship, to be sure, but hearing God's Word preached by a man who handles it properly prepares us to live out the coming week in ways that honor Christ. As we prepare for church tomorrow, therefore, let's pray for our pastors to preach clearly and honestly, and let's listen attentively with a commitment to act on what we hear.
