Excerpt from Prefatory Word: "No one could have undertaken this work of writing Mr. Muller's life-story without being deeply impressed with the opportunity thus afforded for impressing the most vital truths that concern holy living and holy serving; nor could any one have completed such a work without feeling overawed by the argument which this narrative furnishes for a present, living, prayer-hearing God, and for a possible and practical daily walk with Him and work with Him.""
