I have a confession to make.  I am much better at reading books about prayer than I am at actually doing what they teach.  The fact that so many books in this list of 20 have to do with prayer is more of the cry of my heart to grow in this area than in my actual practice.  Old Paths New Power could be considered a companion to Renovation of the Church because it too emphasizes the move away from doing attractional, program-driven ministry.  Old Paths New Power emphasizes the absolute necessity of the power of the Holy Spirit to create a true church, and how prayer is the key to that power.  Too often we depend on programs rather than Holy Spirit power resulting in the fleshly results of apparent success, but an absence of eternal fruitfulness.  For this much needed challenge and corrective, Old Paths New Power makes the cut of 20 “Must Pack” books.
