“What the Church needs to-day is not more machinery or better, not new organizations or more and novel methods, but men whom the Holy Ghost can use — men of prayer, men mighty in prayer. The Holy Ghost does not flow through methods, but through men. He does not come on machinery, but on men. He does not anoint plans, but men — men of prayer.”― E.M. Bounds, Power Through Prayer
