In the mid-20th century, evangelist Leonard Ravenhill penned a work that would become a touchstone for charismatic and evangelical believers longing for spiritual awakening. Why Revival Tarries is not a systematic theology nor a gentle devotional; it is a fiery prophetic indictment of the modern church’s complacency. Ravenhill argues that revival does not tarry because God is unwilling, but because the church is unprepared. By examining his core themes—prayerlessness, the loss of holy sorrow, the absence of Spirit-filled preaching, and the cost of discipleship—one sees that Ravenhill’s diagnosis remains hauntingly relevant. Revival tarries, he contends, because the church has exchanged power for programming, conviction for comfort, and the cross for popularity. The Crisis of Prayerlessness Ravenhill’s most relentless charge is that revival tarries due to a famine of prevailing prayer. He distinguishes sharply between casual prayer and the agonizing, intercessory prayer that preceded historic outpourings—from the Welsh Revival to the Great Awakening. “The secret of revival,” he writes, “is prayer—not the passing prayer of the conventionalist, but the travail of the soul.” Modern churches, he laments, have replaced prayer meetings with committees, and the prayer closet with the boardroom. Without a remnant that prays until heaven moves, revival cannot come. Thus, the first reason revival tarries is that the church has lost its spiritual birthright: persistent, tearful, expectant prayer. The Loss of Holy Sorrow Another barrier Ravenhill identifies is the absence of genuine repentance. He observes that many sermons produce decisions but not brokenness. True revival, however, is preceded by a deep, collective conviction of sin—what he calls “holy sorrow.” The church has become too comfortable with its moral compromises, too entertained by the world, and too quick to pronounce peace without pardon. Ravenhill insists that until believers weep over their own sin and the sin of the nation, revival will remain a distant hope. In short, revival tarries because the church no longer mourns. Preaching Without Fire Ravenhill contrasts the polished, psychological preaching of his day (and ours) with the Spirit-anointed, confrontational preaching of men like John Wesley and George Whitefield. He argues that powerless preaching produces powerless Christians. Where preachers fear man more than God, avoid the topics of hell and holiness, and rely on marketing over anointing, revival cannot break forth. The tarrying of revival, therefore, is linked to the taming of the pulpit. Ravenhill calls for a return to prophetic preaching—uncomfortable, consuming, and dependent on the Holy Spirit rather than homiletical technique. The Cost of Discipleship Finally, Ravenhill contends that revival tarries because the modern church has embraced cheap grace. Believers want blessing without brokenness, power without purity, and revival without radical sacrifice. He reminds readers that every great spiritual awakening came at a great price: sleepless nights, social rejection, and even martyrdom. When the church ceases to count the cost, revival ceases to come. His challenge is uncompromising: “If you are not willing to pay the price, do not expect the revival.” Conclusion Why Revival Tarries is less a book and more a lament—a holy dissatisfaction with the status quo. Ravenhill does not offer a three-step plan for revival, but a summons to the ancient paths: prayer, tears, fiery preaching, and costly discipleship. For those who read it honestly, the book raises a piercing question: Is revival tarrying because God is slow, or because we are unwilling? Ravenhill’s answer is clear. The delay is not in heaven, but in the hearts of those who claim to seek revival while refusing the conditions that alone bring it.
