While John Calvin is renowned for his profound theological writings, his heartfelt prayers often go unnoticed. This collection presents his extemporaneous commentaries on Jeremiah, Ezekiel, Daniel, and the minor prophets, originally delivered as lectures, each accompanied by thoughtful petitions. In his epistle to the King of Sweden, Calvin expressed a desire to limit the circulation of these informal teachings, meant specifically for the benefit of his audience. John Budaeus, in another preface, encourages readers to seek the guidance of the Holy Spirit in their Scripture reading. He highlights the value of the concise prayers included at the end of each lecture, which serve as examples for those who wish to articulate their own prayers through the words of Scripture. Calvins consistent prayer approach, combined with the spontaneous prayers inspired by the Spirit, offers a rich resource for spiritual growth.
