Finding God Faithful in Unexpected Trials
We often find it easy to trust God when things are going well and difficult to trust him when our world is falling apart. But Scripture assures us we can “trust in the Lord forever, for the Lord God is an everlasting rock” (Isaiah 26:4, ESV). In this very personal episode David Zimmer and Bob Kauflin interview Bob’s son, Devon, about the way God has sustained him during some significant trials he and his church have encountered this past year.

Idolatry on Sunday Mornings [Part 2]
We gather each Sunday as the church to hear from God and worship him as he has revealed himself to us in Jesus Christ. But we can subtly shift our worship to secondary matters like music, liturgy, or skill and end up engaging in idolatry. This is the part 2 of two episodes where David and Bob explore the different idols we can worship on Sunday mornings.

How Much Training Do I Need to Lead Congregational Worship?
One Sound + Doctrine listener wrote in to ask, “How much musical or theological training do I need to be effective in leading congregational worship?” While there are a number of factors to consider, Bob and David devote this episode to taking a stab at answering that question.

What is a Woman’s Role in Leading Worship in Song?
More than a few women have asked us how we should view a woman’s role in leading music on Sundays in light of Scriptures like 1 Corinthians 11:33-35 and 1 Timothy 2:11-15. We invited Jeff Purswell, dean of the Sovereign Grace Pastors College, to join us for a conversation on how we can think about this topic in a way that seeks to honor God’s Word as well as the significant role women play in our gatherings.

How Should God’s Word Function In Our Sunday Gatherings?
People sometimes view the music and the preaching on Sunday morning as unrelated. But God intended Scripture to govern, guide, fill, and fuel our times together. What does that mean for how we structure and lead our gatherings? That’s the topic David and Bob discuss with Jeff Purswell, dean of the Sovereign Grace Pastor’s College, on this week’s Sound + Doctrine Podcast.

How Can We Share Musical Opinions Humbly?
Band rehearsals for Sunday morning can sometimes reveal differing thoughts on how songs should be sung, played, and interpreted. How do we share those thoughts humbly, while continuing to pursue musical excellence? That’s the topic David and Bob dig into on this episode of Sound + Doctrine.

Backing Tracks – Blessing or Curse? Or Something in Between?
For about 15 years now, churches have had the option of using instrumental and vocal tracks to supplement or replace live musicians on Sunday mornings. In this episode, Bob and David ask what the benefits and drawbacks of adopting backing tracks might be and consider what the Bible has to say to help us.
