In his introduction to this beautifully written companion to the Evening Cycle of Psalms (as set out in the Church of England's Book of Common Prayer), Michael Sadgrove reminds us that the Psalms have been central to public worship and personal prayer for the entire history of the church. They are indeed one of the world's greatest spiritual treasures- in the words of Martin Luther, 'full of heartfelt utterances'- and are as vital a source of comfort, challenge and inspiration to people of faith today as they have ever been. I Will Trust in You will greatly benefit anyone who wishes to engage more deeply with the riches of the Psalms.
