Rachelle Liggett said: "I remember seeing posts on Facebook of people, who reacted in frustration, anger and embarrassment. As if suggesting: 'how could God have a place in today's world, our world'?"
"My silence felt like denial of knowing God."
In October, Donaghadee teenager Joshua Martin spoke publicly about his faith that God was going heal him.
Miss Ligett told the Belfast Telegraph how she had been diagnosed with an acute form of leukaemia at the age of ten.
"I was then sent to the haematology ward of the Children's Hospital in Belfast, where I was to live for the next few months.
"However, when I was diagnosed my skin colour fluctuated between yellow and white. I was five stone in weight with no body fat and no appetite for food or water. My condition was very severe."
Miss Ligett is adamant that God was responsible for her recovery.
"During prayer, when the hand of a Christian faith healer was laid on my head, I could feel my fingertips and legs and toes tingle with pins and needles.
"I believe this was the cancer exiting my body. After this, everything in my life changed.
"My appetite returned and I started to put on weight. The doctors never again found a cancerous cell in my body."
After missing two years of school she went on to defy expectations and then achieve a first class honours degree in 2014.
In between, she won the Miss Ireland contest in 2011.
"Just this year I was voted Portadown's Person To Be Proud Of for 2015 in my home town, which I am extremely appreciative of."
Miss Ligett admitted that the negative comments made about Joshua Martin on social media "...made me immediately want to scream out in joy and say to these people that I was also cured from cancer through prayer!
"I wanted to tell them that miracles do happen; that it is all true.
"It is clear to me now that it is the will of God that Joshua and I are both here today, that we did not die, but lived to declare the works of the Lord.
"I love the Lord and I am certainly not afraid of what reaction my story brings, because He is my strength and my protector and goes before me in all things."
