The Bible calls us to pray without ceasing, and a longing for night-and-day prayer is sweeping the global church. Prayer rooms are springing up everywhere, from large missions organizations to small local churches. Believers need practical tools to help us sustain joyful, corporate, 24/7 prayer meetings. The Harp and Bowl model is a scriptural, God-focused, dynamic structure that facilitates the flow of sustained and enjoyable prayer for hours. It follows the example of prayer with worship found in Revelation 5, where the elders worshiping around God’s throne hold two things: harps and bowls full of the saints’ prayers. “…fell down before the Lamb, each having a harp, and golden bowls full of incense, which are the prayers of the saints.” Revelation 5:8 This practical guide from the International House of Prayer in Kansas City is based on over twenty years’ experience in corporate 24/7 prayer. Harp & Bowl provides direction for prayers rooms and the musicians, singers, and intercessors who staff them. It includes the mechanics and principles of the Harp and Bowl model, key apostolic prayers from the New Testament, a brief history of night-and-day prayer, a biblical overview of the end-time prayer movement, and a look at intercessory missionaries in the biblical timeline.
