Deuteronomy is possibly the longest sermon ever given, preached by Moses as Israel is about to enter the Promised Land. As Moses exhorts Israel to live faithfully, we discover rich and practical insights about what the God we serve is like, what it means to live his way, the nature of worship, and God’s view on leadership. Most importantly, Paul Barker points us to the difference that Jesus has made, enabling Christians to respond to God more faithfully than Israel did.
