“The Purifying Power of Gethsemane” is the general conference talk often referred to as Bruce R. McConkie’s final testimony. Elder McConkie gave the talk when sick with cancer, less than two weeks before his death. His testimony of Jesus Christ was so influential that Joseph Fielding McConkie called it “one of the most powerful talks ever given in the Tabernacle.” It has also been noted by historian John Turner in Mormon Jesus as a pivotal event that marked a change in how Latter-day Saints talk about the Savior.
