Thirteen days before passing away from cancer, Elder Bruce R. McConkie bore powerful apostolic testimony in his final conference talk: "The Purifying Power of Gethsemane".
Technically it should be titled "The Purifying Power of the Atonement", since it's not the Garden of Gethsemane that purifies, but Christ's Atonement. Moreover, the Atonement did not take place only in Gethsemane, but also on the cross of Calvary. Elder McConkie testifies: "While he was hanging on the cross for another three hours, from noon to 3:00 p.m., all the infinite agonies and merciless pains of Gethsemane recurred."
In this classic talk he invites us to join with him in gaining "a sound and sure knowledge of the Atonement", which Atonement is "the most transcendent event that ever has or ever will occur from Creation’s dawn through all the ages of a never-ending eternity."
Candidly, Elder McConkie was wrong on some things during his lifetime, but on this he was 100% right. In the imperative matters of testimony bearing, and in his apostolic role, I admire him greatly. His last statement is even more powerful listening to him deliver it himself. I can't help but be inspired:
And now, as pertaining to this perfect atonement, wrought by the shedding of the blood of God—I testify that it took place in Gethsemane and at Golgotha, and as pertaining to Jesus Christ, I testify that he is the Son of the Living God and was crucified for the sins of the world. He is our Lord, our God, and our King. This I know of myself independent of any other person.
I am one of his witnesses, and in a coming day I shall feel the nail marks in his hands and in his feet and shall wet his feet with my tears.
But I shall not know any better then than I know now that he is God’s Almighty Son, that he is our Savior and Redeemer, and that salvation comes in and through his atoning blood and in no other way.
God grant that all of us may walk in the light as God our Father is in the light so that, according to the promises, the blood of Jesus Christ his Son will cleanse us from all sin.
