This is a book about God: the God i know, the God whom Israel knew, the God who belongs to be known ever more deeply. Thomas Flowers makes the starling claim that impiety, rather than piety, seems to be necessary if we are to be in a deeper relationship with the lord. People in the old testament do not simply prayed they talked with God, and even talked back to God. Each chapter of God’s invitation is based on around one of the great covenants God made with the people of Israel.
