Miracles are like defibrilators. They can give a jump start to your faith, but they aren't a substitute for it. And miracles don't really prove anything because they can't really be replicated, at least not in a scientific way. Otherwise they wouldn't be miracles, they'd be natural law.
The following miracles are not my own by are related by a person that I find trustworthy. You'll have to make your own judgment about that.
This first one is, I think, very sacred and you should not read it if you feel inclined to ridicule or scoff at it. This is from a talk by Dallin Oaks:
"Another sacred experience is related in the book Tongan Saints. It happened while Elder ‘Iohani Wolfgramm and his wife were serving a mission in their native Tonga...
Their three-year-old daughter was accidentally run over by a loaded taxi. Four of the occupants of the taxi sorrowfully carried her lifeless body to her parents. “Her head was crushed and her face was terribly disfigured.” 20 The sorrowing helpers offered to take the little girl’s body to the hospital so the doctors could repair her severely damaged head and face for the funeral. I now quote the words of her father, Elder Wolfgramm: “I told them I did not want them to take her but that I would ask God what I should do and, if it was possible, to give her life back.”
The helpers took the little girl’s body into the chapel. Elder Wolfgramm continued: “I asked them to hold her while I gave her a priesthood blessing. By then the curious people of the village were flocking in to see our stricken little daughter. As I was about to proceed with the administration, I felt tongue-tied. Struggling to speak, I got the distinct impression that I should not continue with the ordinance. It was as if a voice were speaking to me saying: ‘This is not the right time, for the place is full of mockers and unbelievers. Wait for a more private moment.’
“My speech returned at that moment and I addressed the group: ‘The Lord has restrained me from blessing this little girl, because there are unbelievers among you who doubt this sacred ordinance. Please help me by leaving so I can bless my child.’
The people left without taking offense. The grieving parents carried the little girl to their home, put her body on her own bed, and covered her with a sheet. Three hours passed, and her body began to show the effects of death. The mother pleaded with the father to bless her, but he insisted that he still felt restrained. Finally, the impression came that he should now proceed. I return to his words:
“All present in the home at that moment were people with faith in priesthood blessings. The feeling of what I should do and say was so strong within me that I knew Tisina would recover completely after the blessing. Thus, I anointed her head and blessed her in the name of Jesus Christ to be well and normal. I blessed her head and all her wounds to heal perfectly, thanking God for his goodness to me in allowing me to hold his priesthood and bring life back to my daughter. I asked him to open the doors of Paradise, so I could tell her to come back and receive her body again and live. The Lord then spoke to my heart and said, ‘She will return to you tomorrow. You will be reunited then.’ ” 23
The parents spent an anxious night beside the body of the little girl, who appeared to be lifeless. Then, suddenly, the little girl awoke, alive and well. Her father’s account concludes: “I grabbed her and examined her, her head and face. They were perfectly normal. All her wounds were healed; and from that day to this, she has experienced no complications from the accident. Her life was the miraculous gift from Heavenly Father during our missionary labors in Fo’ui.”
Another miracle related by Dallin Oaks in the same talk.
I had an experience with the gift of tongues in the newly opened country of Bulgaria. In November 1990 we sent missionaries into Bulgaria. A handful of elders entered from Serbia, without any contacts or training in the Bulgarian language. Through their labors and the blessings of the Lord, we soon had 45 Bulgarian members.
In April 1991 I went to Bulgaria with Area President Hans B. Ringger and mission president Dennis B. Neuenschwander. There, most of our members and about 150 investigators assembled in an attractive civic building in Sofia for a fireside at which I was to speak. My interpreter was Mirella Lazarov, a newly baptized member in her 20s. The audience included many professional people and some government officials. I had prayed fervently for guidance in this talk but had little time for preparation.
I began by telling the audience about The Church of Jesus Christ of Latter-day Saints and how we differed from other Christian churches. I then felt impressed to speak about the Apostasy, which I did in some detail. In doing so, I completely forgot that I was speaking through an interpreter who had been a member only five months and had almost no background in the subject of the Apostasy. Forgetful of this, I made no attempt to speak in simple terms but made extensive use of the unfamiliar English words involved in a detailed explanation of the Apostasy and the Restoration.
After the crowd had departed, Sister Lazarov tearfully told me of her unique experience in translating my talk. Despite her fluency in English, she sometimes heard me speak words or express thoughts she did not understand in English. She said that whenever this happened, “another voice” spoke through her so she found herself using words or explaining concepts in Bulgarian that she did not understand in English. I told her to cherish this experience and testify of it to others..."
