I've very surprised to be the first to review what I would think is a Christian classic, similar to George Mueller's autobiography. In a little work of under 150 pages, this missionary wife relates in "trench warfare" stories HOW it is that, "...the kingdom of God is not in word, but in power." 1Cor 4:20 In stark contrast to the Emerging Church i.e. contemplative prayer movement, her story relates that we cannot "...climbeth up some other way...." John 10:1. One could read a number of theological works on "abiding in Christ" to their benefit, but if you would "...receive the kingdom of God as a little child...." John 10:15, read this.
