Most of Calvin’s sermons preached on the Lord’s Day from the Old Testament were based on the Psalms. His New Testament commentaries abound with references to the Psalms. Calvin tells us in an autobiographical note prefaced to his Commentary on Psalms that the Psalter had comforted him in a major way during years of trial (1549–1554).
