John Bunyan, renowned for his literary masterpiece "Pilgrim's Progress," unfolds another gem in the realm of spiritual guidance with his lesser-known work, "Prayer." Penned during his incarceration and initially published in 1652, this concise yet profound book delves into the intricacies of prayer, offering readers a rich understanding of this essential aspect of the Christian life.

Bunyan emphasizes the purpose of prayer as seeking those things God has promised or aligning with His Word, all while fostering a commitment to the well-being of the Church and an unwavering submission to God's will in faith. True to the Puritan style, Bunyan methodically dissects and elaborates on each component of his definition, providing readers with a structured and insightful journey into the practice of Christian prayer. He navigates through the dimensions of sincerity, sensibility, and affection, highlighting the role of Christ and the Holy Spirit in this spiritual discipline.
