Reverberation argues that the Word of God is what creates and sustains a church, and that it should reverberate through the whole of congregational life rather than being confined to the sermon slot. Jonathan Leeman traces how Scripture does its work in conversion and sanctification, then shows the Word at work in preaching, in singing, in prayer, in discipling conversations and in the ordinary speech of members to one another.

The book suits pastors thinking about what their church is actually built on, elders and worship leaders planning services, and members who want to understand why the sermon matters and what to do with it afterward. Leeman writes from 9Marks and the book reflects that concern for healthy local church practice.
