Many years ago, as a high school ­student, I had the opportunity to become acquainted with several Catholic nuns who lived in a convent in my hometown and worked in the nearby Catholic hospital. As their schedules permitted, I often spent time with them, walking in the park or visiting in the parlor of the convent. One afternoon I happened to be talking with Sister Columba. She was a tiny, elderly woman who had been a member of the Irish Army before she became a nun. That day she was sharing with me the profound love that she had for our Savior, Jesus Christ, and as she spoke, tears were streaming down her face. It was a powerful spiritual moment that touched me in the deepest center of my being. After I left that day, I pondered Sister Columba’s testimony of Christ. I had grown up as a member of The Church of Jesus Christ of Latter-day Saints, and I had attended my church meetings and seminary classes. I had frequently borne testimony that the gospel of Jesus Christ was true. And yet I couldn’t comprehend how it could be, with all of this truth, that I had never felt anything for Jesus Christ—certainly nothing like the level of worship and gratitude that I had experienced from Sister Columba. That afternoon with this frail nun in the quiet parlor of the convent became the definitive moment of my spiritual growth, as it launched a quest to know my Savior that has shaped my entire life. The most critical point, which I have at last come to comprehend, is the absolute centrality of Jesus Christ and His Atonement to every aspect of our lives. Because of that centrality, the most significant challenge for us is to learn to grasp this center and to build our lives upon this secure foundation. This injunction is nothing new. If we really look at it, this one fact—the centrality of Christ and the Atonement—builds the focus for all the religious instruction that the Church conveys. The question that I have been grappling with is this: Since Christ and His Atonement are so clearly the center toward which all our religious experience leads, why is it often so difficult for us to actually connect with that center and to make it our own in an active way? Of course there are many ways to answer this question, but today I would like to share some insights that I have found as I have pondered this ­question in my own life. Mortal Perception and Spiritual Perception We are born into this world as somewhat awkwardly composite beings in which an eternal spirit has been enclosed in a mortal, physical body. This dividedness comes, I believe, because these two disparate elements—mortal body and eternal spirit—provide us with two distinctly different mechanisms for comprehending the world. I will call these “mortal perception” and “spiritual perception.” Mortal perception is the means of understanding that is provided by our physical body. […]
