My friend, Paul Clark, has recently started a blog where he posts the excellent articles he sends out to pastors, worship pastors, music ministers, etc., in conjunction with his work as Worship Specialist for the Tennessee Baptist Convention. Paul thinks biblically, congregationally, and carefully about corporate worship. These articles are the expression of his own heart, which is certainly tuned to God's redeeming grace. I encourage you to read his most recent post, Disconnected Prayers in Public Worship, and to check back regularly for future articles.
And if you are a pastor, I also encourage you to consider bringing Paul to your church to lead in a Worship Renewal Through Congregational Singing Weekend, a recent project that Paul has been working on and just begun offering to local churches.
