Leading Your Church Through Change
 There is something profound about a church that faithfully carries out its meetings with a steady consistency, week after week, month after month, year after year. It testifies to the unchanging truths we trust in, rely on, and cling to. But what happens when leaders realize there’s something they could do something better or differently? What if God reveals an area that could be shored up, strengthened, added, or done away with? That’s the topic Bob and David tackle on this episode of Sound Plus Doctrine.

Worshipping a Big God in a Small Church
 It can be discouraging to attend a worship conference where everyone seems to assume your church has a large staff, several music teams, and an unlimited budget. For most of us, that situation is far from reality. In this episode, Bob and David talk about how to make the most of limited resources, maintain a strong faith in God’s plan, and serve with contagious joy.

“Christian worship is the God-enabled response of his redeemed people to His self-revelation that exalts God’s glory in Christ in our minds, affections, and wills in the power of the Holy Spirit.” – Bob Kauflin
“Corporate worship is God’s Spirit-enabled and Word-governed gift, initiated by the revelation of God in Jesus Christ, for his covenant people to gratefully assemble in space and time to witness to the worth and work of God in Christ by the Spirit through proclamation, prayer, singing, and the sacraments, as they receive from Christ, act in him, and long for him to come again.” – Devon Kauflin

Hard Conversations With Your Pastor
 What do you do when you lead the singing in your church, but it’s obvious that you and your pastor have disagreements? “My pastor isn’t involved.” “My pastor micro-manages everyone around him.” “My pastor wants me to lead songs I’m not very excited about.” In this episode, David, Devon, and Bob take some time to talk about helpful and unhelpful ways of having those hard conversations.
