Gene Higgins explores the life, medical contributions, and spiritual conversion of Sir James Simpson (Isaiah 53). He examines Simpson's pioneering work with chloroform as an anesthetic, the intense professional and theological opposition he faced, and the biblical precedent he used to defend the use of pain relief in medicine from Genesis. He contrasts Simpson's early skepticism with his profound personal realization of substitutionary atonement, emphasizing that his greatest discovery was not scientific, but rather that Christ was able to save him.
