His penetrating scientific mind enabled him to tackle with acuity topics as ambitious as the way to become like Christ. This is the topic of Drummond's seminal address, "The Changed Life," a staple of the legacy that, according to Drummond's biographer, "changed the spiritual climate of his half-century." This essay is grouped under the following topics: "The Changed Life," "Formula of Sanctification," "The Alchemy of Influence," and "The First Experiment." Now, with this audio production, these beautiful and deeply moving reflections can once again be enjoyed as originally intended: as an oral sermon designed to inspire a positive change within the listener.
