What is the gospel? It seems like a simple question, yet it has been known to incite some heated responses, even in the church. How are we to formulate a clear, biblical understanding of the gospel? Tradition, reason, and experience all leave us ultimately disappointed. If we want answers, we must turn to the Word of God. Greg Gilbert does so in What Is the Gospel? Beginning with Paul's systematic presentation of the gospel in Romans and moving through the sermons in Acts, Gilbert argues that the central structure of the gospel consists of four main subjects: God, man, Christ, and a response. The book carefully examines each and then explores the effects the gospel can have in individuals, churches, and the world. Both Christian and non-Christian readers will gain a clearer understanding of the gospel in this valuable resource.
