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.
