It has been eight years since Christian singer Natalie Grant first experienced the joys of motherhood. Looking at her now with three beautiful young girls in tow, it is hard to imagine that she was once told that she will never become a mother.

In an op-ed piece for Fox News, the singer is now sharing that difficult moment in her life with the hope of inspiring other women never to lose hope on having children of their own.

"I'll never forget the day I was told my husband and I would never be able to conceive children naturally," she writes. "I received a phone call from the doctor delivering the news moments before I was to take the stage at the famed Ryman auditorium in Nashville."

She was just about to sing a duet with Wynona Judd, and despite it being a dream come true for her, the news caused her to wallow in grief.

"I'm thankful that was not the end of the story. Today, by God's grace, I am a mother to three. My twin daughters are 8 and my youngest daughter is four," she shares. "I'm incredibly grateful that we live in a country where I had skilled physicians and amazing advances in medicine that allowed my husband and I to conceive our twins."

Grant then said that faith and science cannot be separated, since it is only through the will and power of God that "miraculous medical advancements are even possible."

And as happy as she is already with her twin daughters, God decided to bless Grant with another baby girl. "I am also grateful that sometimes God gives us miracles we never even ask for. My third daughter was a shock and awe baby. No medical intervention, just a God-wink, because she was conceived naturally," she says.

Grant knows that there are so many women out there who are begging God for the same miracle that He has decided to bless her with, and her thoughts and prayers are constantly with them. Once they become mothers themselves, Grant assures them that it will be the greatest and hardest role they would ever have to take on.

"My heart is consistently grateful that I gave birth to three children and I am regularly in awe, even when the nights are long and the cups of coffee are many!" she writes.

When she recently went back to the Ryman auditorium and found herself in the exact same dressing room where the initial call came, Grant notes that the mood has shifted.

"The last time I was there, I quietly sobbed in a corner. This time, however, the sound of girlish giggles filled the air as my daughters twirled and danced in the room. Earlier that same day, my husband had the honour of baptising our twin daughters at our home church," she says. "It was a day for the books. And my heart was then, as it is now, bubbling with gratitude and thankfulness that even on the hardest of parenting days, I AM A MOTHER."
