J. Oswald Sanders gives practical how-tos and examples to follow. He covers different aspects of prayer--worship, thanksgiving, confession, intercession & petition. Then he gives us Jesus' example, praying the promises of the Word, praying God's will, praying in the Spirit, praying with persistence, and unanswered prayer. He looks at Paul, authority in prayer, prayer takes time, praying in unity with other believers. He looks at praying for those in authority, for workers, for revival.
Very practical suggestions of how to pray and who to pray like and what to pray for. Easy to read as well.
