In six short chapters, originally preached as sermons, Carson takes his readers on a survey of the main themes of the Sermon of the Mount in Matthew 5–7. While there is not the space for as much detail as would be found in an expositional commentary, this work complements that approach with more practical application than would be typically included in such a commentary. Indeed, Carson frequently pulls no punches when dealing with the state of the church today, but does so in a gently irenic and occasionally humorous way, such as when he criticises modern Christian songs for portraying God as a ‘great big wonderful teddy bear’ (p. 70).
Carson reads the central theme of the Sermon on the Mount as the kingdom of heaven, and bases his chapters around that. In this view the beatitudes exemplify the character needed to inherit the kingdom, and the first of these (‘Blessed are the poor in spirit, for theirs is the kingdom of heaven’) is foundational to the rest. He says, ‘poverty of spirit is the personal acknowledgment of spiritual bankruptcy. It is the conscious confession of unworth before God. As such, it is the deepest form of repentance.’ (p. 20) The understanding this entails is that following the demands of Jesus is unattainable except by grace. This hard-hitting approach is repeated throughout the book, and frequently led me to prayer in confession of sin and adoration and thanks for God’s grace. Carson’s humility shines through, and his willingness to apply the text to his own life is evident particularly in dealing with the call to be discerning, but not judgemental found in the beginning of Matthew 7.
The relationship between Jesus’ Sermon and the Old Testament is not explored in detail, but rather functions as an undercurrent to the whole exposition. ‘The Old Testament,’ Carson explains, ‘points forward to Jesus and the kingdom he announces and finds its real continuity in them.’ If the coming kingdom is the main theme, just as important is the idea that this kingdom is the fulfilment of the Old Testament. Jesus’ demands are if anything greater than the Old Testament commands which further highlights man’s moral bankruptcy and the need for salvation.
There are two helpful appendices which explore in more detail different theological and critical approaches to the text. Even here Carson’s warm-hearted approach is seen as he refuses to dismiss any position but instead shows what can be learned from approaches he himself disagrees with. Perhaps best suited to another appendix, but instead presented as an excursus to Carson’s final chapter is a discussion of the relationship between Jesus’ teachings as found in the gospels and the letters of Paul. This is not to say that the material is not worthwhile – it is an extremely clear summary of the evidence, and anyone struggling to see how Paul fits in with the rest of the New Testament would be wise to read it carefully.
All in all, this book is a rich mine of teaching, and there is much to enjoy as well as challenge. I’m sure it would repay many re-readings in years to come.
