In this episode of Pastors Talk, Mark Dever sits down with Sean DeMars to talk about his book Redemption Song, a short and approachable primer on congregational singing. Using Moses' song in Exodus 15 as a lens, they explore why God's people sing, how the regulative principle guides our worship (and why it needn't be scary or restrictive), and why singing is part of the word ministry of the church that pastors, not just music leaders, are accountable for.
