Christian author Lysa TerKeurst, who is also the founder of Proverbs 31 Ministries, is thanking God for saving her life, and she describes her cancer treatment as nothing short of a miracle.

"Thank you for praying for me," she writes on her Facebook page. "The surgeon that removed half of my colon that had twisted and distended to the size of a large football called me on Friday to tell me there was no sign of cancer in the pathology report. Praise God."

TerKeurst was already in high spirits after receiving that report, but what the surgeon told her after left a deeper impact. "Lysa, I don't like throwing around the word miracle. But the fact you survived this is a miracle. The pathology report showed your cells were in a state of death," the surgeon told her.

Overwhelmed by God's grace, TerKeurst was left speechless, and she couldn't find anything else to say other than "Thank you, God."

"Thank you friends who prayed me through this. Thank you to this surgeon who finally figured out why I was in excruciating pain for days and days in that hospital bed. Thank you that I still get to do life. So, here I sit," she continues. "But this quiet Monday morning is different."

TerKeurst says that as a result of her experience with cancer, she has come to the "sacred realisation" that each day is a gift from God. Even though she has 15 staples on her stomach, she has a "complete refocus" on how precious every second of every day is.

"When the baby is crying and the deadlines are pressing and the stress is mounting and the enemy whispers 'just get through this crappy day,' look up and shame the enemy back to hell by acknowledging today is a gift," she urges. "A gift from a good, good Father. And then look, seek, and dive deeply into what a true gift it is."
