During the Diamond Jubilee Service in St Paul’s Cathedral, the children’s choir sang, The Call of Wisdom. This month we take up that theme. We have asked our prayer authors to reflect on a part of the Bible knows as the “wisdom literature” – five books in the middle of Old Testament: Job, Psalms, Proverbs, Ecclesiastes and Song of Songs. They will encourage us to “wise up” as we pray through these earthy pieces of Hebrew writing.
