Lourdes, France has a reputation for miracles. The small town drew international attention when, in 1858, a young girl named Bernadette claimed to see a vision of Mother Mary. Since then, Lourdes has been a destination for pilgrims and those seeking healing. Jean-Pierre Bely was one of those people.

In 1987, he traveled to Lourdes. Years ago, Jean-Pierre had been diagnosed with multiple sclerosis, an autoimmune disorder that attacks the body’s central nervous system. He was now confined to a wheelchair. But during a service in Lourdes, Jean-Pierre felt something strange.

“As the priest was giving me unction on the forehead and hands, I had the impression that everything was turning around me,” he was later quoted in the book Near-death Experiences Examined: Medical Findings and Testimonies from Lourdes. “In a fraction of a second I lost all sense of time and space. God was coming to cure my heart. I was invaded by a powerful feeling of liberation and peace that I had never experienced before.”

After that experience, Jean-Pierre began to feel a tingling in his legs. A few days later, he took his first unaided steps in years. Subsequent examinations would show only minor traces of the illness that had once dominated his life. Though still a medical mystery, Jean-Pierre’s cure was deemed an official miracle by the Vatican in 2002

His doctors were baffled. They didn’t know why Luke had been sick and they had no explanation for why he’d improved almost overnight. But Luke’s mother, Jan Burgie, had an answer: Prayer.

As her son lay in his hospital bed, Jan had called nuns from a local convent—Sisters of St. Francis of Perpetual Adoration—and asked them to pray for him. Over the course of nine days, they did just that, praying to Mother Maria Theresia, the nun who began their order back in 1863. Within a month, the little boy had made a full recovery.

“I just remember Luke’s brother saying, ‘Jesus’ healed Lukie! Jesus healed Lukie!’” Jan told FOX31.

Fourteen years later, the Vatican declared Luke’s healing a miracle and Mother Maria Theresia was named Saint Maria Theresia.

For six months, he wasted away. When 4-year-old Luke Burgie fell ill with a mysterious stomach virus in 1998, doctors struggled to find a diagnosis. Then, as suddenly as they had developed, Luke’s symptoms disappeared.

In July of 2013, the 12-year-old Kali Hardig visited a water park. A few days later, her parents were rushing her to the hospital. She was complaining of a headache and had a fever of 103 degrees. Tests revealed that Kali had contracted parasitic meningitis. It’s a rare infection caused by brain-eating amoebas. It’s also a deadly one.

Kali was quickly put on antibiotics, but her doctors prepared her family for the worst. Even with treatment, the infection’s survival rate was less than 1%. At that time—in the whole of North America—only two people were known to have survived. But Kali would become the third. Not only that, but, six months later, she’d made a complete recovery.

“It was God’s grace,” Dr. Matt Linam said in an interview with Reader’s Digest when asked how Kali survived. “Other than that, it was countless little things that went her way, countless little miracles that happened every day and made the difference between life and death.”
