I
A Promise with the Lord
Seoul, 1950. A childhood no one wanted, nine years of illness, and the title He gave her before she would speak.
“Go, I will put the words in your mouth.”
Pages 1 – 38
Act 00 — An autobiography of answered prayer
“My cup overflows.”PSALM 23:5
Nine years of an illness no doctor could name. One prayer in a Kentucky church. Then a lifetime of dreams, healings and provision — told in her own voice, transcribed from the tapes readers passed hand to hand for twenty-five years.
Act 01 — Where it begins
Born in Seoul on 22 January 1950 — the third child in a house that had hoped for a son, fatherless by that summer of the war. She learned English from an American stepfather, married into a well-known Kentucky family, raised two children, built a gardening business. Then the illness came, and no one could name it.

“The moment I felt a sense of healing, life returned from the soles of my feet upward — a beauty I had never known: the fragrance of Jesus' love.”

Act 03 — Three nights a week, for ten years
“Could you not watch with me one hour?”
The sentence from Gethsemane that would not leave her. She prayed a year and a half to learn how to stay awake — then kept the vigil for a decade.
Chapter two · pages 52 – 54
Act 04 — A ledger
She asked God what her household needed, then went to the market. Recorded in her own accounting — prices and all.
“Even things I'd asked long ago and forgotten, He remembers and answers.”
Three passes down the aisle and nothing. On the fourth she saw them — everything she needed. She kept the receipt.
Prayed for before a church potluck. One sack fed the church, two went to families who needed them, and one was still left at home.
She had asked once, long before, to eat pears to her heart's content — and forgotten. The Spirit reminded her in the aisle.
Usually more than two dollars each. They came in exactly the quantity she needed — as did heaps of cabbage the week she asked what to carry when visiting.
Act 05 — The witnesses
Letters printed in the front of the book, from Kentucky, Tennessee, Michigan, Oregon and Dublin — several about healing that followed her prayers.
“We fasted and prayed; the dyslexia left.”
His niece's learning disability went. Her mother had seventeen ailments — constant poison-ivy reactions, various allergies. “Sun prayed, and all of them disappeared.”
Dr. John Garrett, M.D. · Foreword
“She claims God's promises with childlike faith.”
He writes that she carries a burden for Koreans, helped establish a Korean church, and often aids the sick through prayer. “I welcome her prayers for me.”
Pastor Bobby Wint · Kentucky
“I regained my first love.”
His once-zealous prayer life had waned. Her testimony exposed the lack and pushed him to restore it — “now I claim the promises.”

The author
Born Seoul, 1950 · Lawrenceburg, Kentucky
She married into a well-known Kentucky family — her father-in-law a racing commissioner who bred Little Trot, the smallest racehorse in America. Of five children she was the one he loved best. None of that is what the book is about.
It is about the illness that nearly killed her, the prayer that ended it, and everything since: evangelising, feeding the hungry, taking the homeless into her home, praying for the sick — in Kentucky, Virginia, New Jersey, Florida, and wherever churches have asked. In Tampa she was given the floor with no time limit and spoke for four and a half hours.
She is the widow of Colonel Roger Lambert, U.S. Army, a veteran of Vietnam and Iraq.
“I am nothing — to be honest, nothing. I have no famous name; I am just a wife to a humble husband and a mother of two blessed children.”
