This year being the 400th anniversary of the birth of Oliver Cromwell, it is fitting that 'To honour God': The spirituality of Oliver Cromwell should be the first title in our series 'Classics of Reformed Spirituality.' Editor Michael Haykin provides an introduction and brief study of Cromwell's spirituality through a consideration of his view of divine providence, conversion and activism. A chronology of the life of Cromwell is followed by 30 selections from his letters, speeches, sayings and prayers. These selections are footnoted with interesting historical detail and include biblical references.
