A series of reflective, pastoral talks that explain the meaning and mission of prayer, arguing that prayer is the chief outlet of spiritual power and a means of cooperating with God. Topics include prayer's role in spiritual conflict, five avenues of spiritual influence (character, speech, service, money, and prayer), common hindrances and delays, practical methods for relationship and listening, discerning God's will, assurance in intercession for others, and the prayer habits of Jesus. The tone is devotional and practical, offering guidance to cultivate persistent, receptive prayer that shapes personal life and wider ministry.
