Prayer, Return of Prayer and the Saint's Jewel by John Bunyan
Three Bunyan gems bound in one volume: a manual on fervent prayer, a meditation on God’s answers, and a treatise on the pearl of Christian assurance. The tinker-preacher’s earthy metaphors and biblical candor turn private prayer from a duty into a delight and transform anxious souls into jewel-bearers who know they are loved by the King.
