On Facebook, President Nelson shared an incredible and powerful story of two little girls he operated on who visited him one night from beyond the veil.
President Nelson told more of the story in October 2015 general conference:
“Fifty-eight years ago I was asked to operate upon a little girl, gravely ill from congenital heart disease. Her older brother had previously died of a similar condition. Her parents pleaded for help. I was not optimistic about the outcome but vowed to do all in my power to save her life. Despite my best efforts, the child died. Later, the same parents brought another daughter to me, then just 16 months old, also born with a malformed heart. Again, at their request, I performed an operation. This child also died. This third heartbreaking loss in one family literally undid me.
“I went home grief stricken. I threw myself upon our living room floor and cried all night long. Dantzel stayed by my side, listening as I repeatedly declared that I would never perform another heart operation. Then, around 5:00 in the morning, Dantzel looked at me and lovingly asked, ‘Are you finished crying? Then get dressed. Go back to the lab. Go to work! You need to learn more. If you quit now, others will have to painfully learn what you already know.’”
In the April 2016 Priesthood Session, President Nelson told the rest of the story—a beautiful ending for both him and the grieving family.
Here's how he summarized it on facebook just yesterday:
"Congenital heart disease afflicted three children born to Ruth and Jimmy Hatfield. Their first son, Jimmy Jr., died without a definitive diagnosis. I entered the picture when the parents sought help for their two daughters, Laural Ann and her younger sister, Gay Lynn. I was heartbroken when both girls died following their operations. Understandably, Ruth and Jimmy were spiritually shattered.
"Over time, I learned that they harbored lingering resentment toward me and the Church. For almost six decades, I have been haunted by this situation and have grieved for the Hatfields. I tried several times to establish contact with them, without success.
"Then one night last May, I was awakened by those two little girls from the other side of the veil. Though I did not see or hear them with my physical senses, I felt their presence. Spiritually, I heard their pleadings. Their message was brief and clear: 'Brother Nelson, we are not sealed to anyone! Can you help us?' Soon thereafter, I learned that their mother had passed away, but their father and younger brother were still alive.
"Emboldened by the pleadings of Laural Ann and Gay Lynn, I tried again to contact their father, who I learned was living with his son Shawn. This time, they were willing to meet with me.
"In June, I literally knelt in front of Jimmy, now 88 years old, and had a heart-to-heart talk with him. I spoke of his daughters’ pleadings and told him I would be honored to perform sealing ordinances for his family. I also explained that it would take time and much effort on his and Shawn’s part to be ready and worthy to enter the temple, as neither of them had ever been endowed.
"The Spirit of the Lord was palpable throughout that meeting. And when Jimmy and Shawn each accepted my offer, I was overjoyed! They worked diligently with their stake president, bishop, home teachers, and ward mission leader, as well as with young missionaries and a senior missionary couple. And then, not long ago, in the Payson Utah Temple, I had the profound privilege of sealing Ruth to Jimmy and their four children to them. Wendy and I wept as we participated in that sublime experience. Many hearts were healed that day!"
