Each volume uniquely combines the insights of an experienced Bible exegete (trained in interpretation) and a homiletician (trained in preaching). These two authors work together to explain the essential message for the original listeners or readers, unpack its timeless truth, and then provide a contemporary restatement and communication of insights for the key biblical concept. Every book is a resource designed and written with the real needs of the pastor and teacher always in sight, providing many ways to creatively express the principal thought in a biblical passage.

Based on the Big Idea preaching model, Kerux enhances the reader's ability to deliver a message that is biblical, cohesive, and dynamic. In Numbers, Joel Barker and Steve West illuminate the enduring importance of this notoriously difficult text for preachers. God's commitment to both his people and his promises claims center stage in understanding this Old Testament record of the covenant people. Through the lens of an ancient time and faraway culture, Numbers emphasizes God's overwhelming holiness and the proper human responses of worship and trust. Barker and West guide expositors in shepherding their congregations through the book of Numbers and its themes of worship; disobedience and grumbling; judgment and restoration; anticipating of promises; and even leadership, all of which relate to God's people today.
