Leonard Ravenhill, in an interview with David Mainse, emphasizes the critical need for prayer in ministry, arguing that a lack of prayer life among preachers leads to a spiritually stagnant church. He reflects on the early church's commitment to prayer and contrasts it with the modern church's focus on organization and performance. Ravenhill calls for a revival of genuine prayer and intercession, suggesting that the church must return to its roots of seeking God earnestly. He also highlights the importance of preachers dedicating time to prepare spiritually, not just intellectually, for their messages. Ultimately, Ravenhill urges ministers to prioritize their prayer life to foster a vibrant and impactful church.
