‘Prayers on the Psalms is a triple treasure to me. It was edited by my beloved mentor David B. Calhoun, who is truly a gift to the church, it is drawn from the great Scottish Psalter of 1595 and the translated French prayers of Huguenot pastor martyr Augustin Marlorat, and it is based on the Psalms God has given his church to sing and pray in joy and tears. Read it devotionally and pray it passionately.’ — Ligon Duncan
