A Call to Prayer was one of J.C. Ryle’s best received works in his day and has remained so ever since. It is a direct exhortation to pray fervently and without ceasing. “I want the times we live in to be praying times. I want the Christians of our day to be praying Christians. I want the church to be a praying church. My heart’s desire and prayer in sending forth this tract is to promote a spirit of prayerfulness. I want those who never prayed yet, to arise and call upon God, and I want those who do pray, to see that they are not praying amiss.”—from the Conclusion.
